B Correct answer
Explanation

The Earth's actual rotational period (sidereal day) is 23 hours, 56 minutes, 4 seconds - the time to rotate 360 degrees relative to distant stars. The 24-hour day is the solar day (time between noons), slightly longer because Earth also orbits the Sun. Option C is the sidereal day with 1 extra rotation per year accounted for.

A Correct answer
Explanation

Earth's sidereal rotation period - the time for one complete rotation relative to distant stars - is 23 hours, 56 minutes, and 4.09 seconds. This is slightly shorter than the 24-hour solar day because Earth is also orbiting the sun, so it needs to rotate a bit extra to face the sun again.

C Correct answer
Explanation

The time is taken by the intervals between strikes. 6 strikes have 5 intervals, so each interval is 6/5 = 1.2 seconds. 11 strikes have 10 intervals. 10 intervals × 1.2 seconds = 12 seconds. 11 is a common distractor that ignores the interval logic.
