Types of computer software – UGC NET Question

Statements A, B and C correctly describe major categories of computer software, while statement D is incorrect. System software does manage hardware and provide a base for other programs, application software does handle specific user tasks, and utilities support maintenance and optimisation. Firmware, however, is typically stored in non-volatile memory on hardware devices and not always on removable media. Therefore, the combination that includes A, B and C but excludes D is the only correct answer.

Option A:
Option A includes statements A, B and C and omits D, so it contains exactly the true statements. It recognises the distinct roles of system, application and utility software in a computer system. Because it does not include the false claim about firmware storage, this option accurately represents the set of correct statements.

Option B:
Option B combines A and D only, which makes the set both incomplete and partly wrong. While statement A is true, statement D wrongly suggests that firmware is always stored only on removable media. It also ignores statements B and C, which are correct, so this option cannot represent the full set of correct statements.

Option C:
Option C groups B, C and D together, mixing true and false information. Statements B and C are correct descriptions of application and utility software, but statement D is incorrect about firmware. By excluding statement A, which is also true, and including a false statement, this option cannot be accepted as correct.

Option D:
Option D includes all four statements, so it brings in the incorrect statement D along with the true ones. Because a correct answer must contain only true statements, including D makes this option invalid. Even though A, B and C are correct, the presence of the false statement prevents this combination from being the right answer.
