Answer

Exam answer

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

Explanation

The clock is the standard illustration of a nested loop: for every one move of the hour hand (outer loop, 12 positions) the minute hand completes a full 60 positions (inner loop). The inner loop runs completely for each single pass of the outer one, which is exactly what nesting means — and the reason states that relationship, so it explains the assertion. Total inner runs: 12 x 60 = 720.

In words

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