Which of the following statements are true?

1.CPU speed is measured in kilobytes (KB) and gigabytes (GB)

2.The size of a monitor is measured diagonally across the screen

3.Laser printer resolution is measured in dots per inch

A1 & 2 only

B1 & 3 only

C2 & 3 only ✓ Correct

D1, 2 & 3

Correct answer: (C) 2 & 3 only

Explanation

A monitor's size measured diagonally and laser resolution measured in dots per inch are the true statements.

Statement 2 is right because screen size is quoted as the diagonal length.

Statement 3 is right because print sharpness is rated in dots per inch.

Statement 1 is wrong because CPU speed is measured in gigahertz, not kilobytes or gigabytes.

Kilobytes and gigabytes measure storage or memory capacity instead.

Matching the right unit to each device avoids common confusion.
