2. B. i-2, ii-3, iii-1
3. C. i-2, ii-1, iii-3 (Correct answer)
4. D. i-1, ii-3, iii-2

Correct Answer

Option C — i-2, ii-1, iii-3

Detailed Solution & Explanation

The correct answer is i-2, ii-1, iii-3.

Key Points

• Operating System — 2 (Security Management): among the OS's core duties is controlling access, authenticating users and protecting data.
• Input Device — 1 (Scanning Devices): scanners feed data into the computer, so they are input devices.
• Output Device — 3 (Projectors): a projector displays the computer's output onto a screen.
• The correct mapping is therefore i-2, ii-1, iii-3.

Additional Information

• Note how this question and Q64 both test the input/output boundary from different directions — scanners as input, projectors and monitors as output.
• Security management covers user authentication, file permissions, encryption support and defence against unauthorised access.
