Lossy compression removes less perceptible details from media to reduce file size, accepting some loss of quality. Formats like JPEG and MP3 use lossy techniques to achieve efficient storage and transmission. The trade off is between file size and fidelity. Thus, the technique described is lossy compression.

Option A:
Option A is correct because lossy compression is defined by irreversible data loss during compression, particularly in multimedia.

Option B:
Option B, lossless, compression maintains all original information and does not fit the permanent data removal mentioned.

Option C:
Option C, archival, compression suggests long term storage and may require lossless methods, not quality loss.

Option D:
Option D, incremental, compression is not a standard term in this context.

Multimedia combines several types of content to create richer learning experiences. Learners may read text, listen to narration, watch animations and interact with diagrams in a single module, which can support different learning styles and increase engagement.

Option A:
Printed text alone represents a single medium and does not exploit the audio or visual capabilities of ICT, so it does not satisfy the notion of multimedia.

Option B:
This option correctly states that more than one medium is used together in a coordinated way, matching common educational tools such as interactive tutorials and video-enriched presentations.

Option C:
A single static picture is just one medium and offers limited interaction; it lacks the combined sensory elements associated with multimedia learning.

Option D:
Handwritten notes on a blackboard are traditional, non-digital teaching aids and do not represent multi-modal digital content in the ICT sense.

Multimedia technology integrates various media elements to enrich learning experiences. By combining visual, auditory and sometimes interactive components, it caters to different learning preferences and can make abstract concepts more concrete. This integration of multiple media forms is precisely what the term multimedia denotes.

Option A:
Option A, unimodal, would imply using only one mode of presentation, which contradicts the description of using several media together.

Option B:
Option B is correct because multimedia explicitly refers to the coordinated use of more than one medium, matching the idea of text, images, audio and video combined.

Option C:
Option C, monolithic, suggests something uniform and indivisible, which is not the intention of varied media integration.

Option D:
Option D, textual, would focus solely on written words and leave out the other media mentioned.

Statements A, B and C correctly explain the concepts of hypertext, multimedia and hypermedia, while D contradicts the core idea of user choice. Hypertext systems are specifically designed to give users freedom to follow different links and paths. Hypermedia extends this by combining linking with multimedia components for richer experiences. Thus, the statements A, B and C together form the correct set.

Option A:
Option A is correct because it includes all three true statements and excludes D, which misrepresents hypertext as strictly linear. It portrays how linking and media integration support exploratory learning in ICT environments.

Option B:
Option B is incorrect because it lists only A and C as correct and omits B. Since multimedia elements are central to hypermedia, understanding their combination with hypertext requires acknowledging B as well.

Option C:
Option C is incorrect because it includes B, C and D and therefore accepts D. While B and C are true, D wrongly claims that hypertext enforces a single sequence, so this combination cannot be accepted.

Option D:
Option D is incorrect because it treats all four statements as correct, implicitly validating D. Accepting a statement that denies user choice in hypertext contradicts standard definitions of hypertext and hypermedia.
