What is the degree measure of the acute angle formed by the hands of a 12-hour clock that reads exactly 1 o’clock?

A. 15°
B. 30°
C. 45°
D. 60°
E. 72°

[ All-around-the-clock ] is 360 degrees.
Each hour is 1/12 of [ all-around ].
(1/2) of (360) = 30 degrees.
That's Choice-'B'.

At 1:00, the hour hand is at 30 degrees and the minute hand is at 0 degrees. The acute angle between them is 30 degrees. Therefore, the correct answer is option B (30°).
