Answer

Exam answer

(a) Both (A) and (R) are true and (R) is a correct explanation of (A)..

Explanation

Both statements are true, and the reason genuinely explains the assertion. Without break, control falls from the matching case into every case below it — that is fall-through. break transfers control out of the switch as soon as one case has run, which is precisely why fall-through is avoided. In assertion-reason questions always ask two things: are both true, and does the second explain the first?

In words

Both (A) and (R) are true and (R) is a correct explanation of (A)..
