D Correct answer
Explanation

Between noon and midnight, there are 12 hours. The minute hand completes 12 full rotations while the hour hand completes 1 rotation. The minute hand laps (crosses) the hour hand 11 times in those 12 hours. Since we want the times BETWEEN noon and midnight (excluding the endpoints where they're already together at noon and will be together at midnight), the answer is 10 crossings.
