A Correct answer
Explanation

The hour and minute hands cross 11 times in every 12-hour period. At noon and midnight, they are already coincident. Between noon and midnight (12 hours), they cross 10 times, not 11 or 12. The math involves the minute hand gaining 11 laps on the hour hand every 12 hours. Option A (10) is correct.
