Effective use of presentation slides – UGC NET Question

Statements A, B and D are correct, while C is the only wrong statement. A is true because slides packed with long paragraphs increase cognitive load and make it harder for students to follow the key message. B is true as relevant visuals, when integrated with verbal explanation, can make abstract concepts more concrete. D is true since readable fonts and good contrast are basic requirements for all students to see the content. C is false because simply reading slides verbatim without elaboration often reduces engagement and can lead to passive listening.

Option A:
Option A correctly singles out C only as the wrong statement. It recognises that good slide design avoids overcrowding, uses supportive visuals and ensures readability, while rejecting the idea that reading slides word-for-word is always engaging. Therefore this option precisely matches the set of wrong statements and is the correct answer.

Option B:
Option B misclassifies A and C together as wrong. Although C is wrong, A correctly warns against overcrowded slides and is fully aligned with multimedia learning principles. Including A among wrong statements makes this option inconsistent and invalid.

Option C:
Option C labels C and D as wrong, but D is actually a correct guideline emphasising readability through appropriate font size and contrast. Treating D as wrong contradicts basic design recommendations for instructional materials. Hence C and D only cannot be accepted.

Option D:
Option D groups A, C and D as wrong and thus incorrectly treats both A and D as false. Since A and D are sound principles of effective slide use, this combination wrongly inflates the number of wrong statements and is therefore not the correct answer.
