Thank you for posting your question here at . I hope I would be of great help to you.

This question can be easily answered just by looking at your clock. When the clock reads 9:30, that means that the hour hand is pointed to 9, and the minute hand is pointed to 6 (since 30 is a multiple of 6 and 5). Since the hands are perpendicular to each other, the angle formed is 90 degrees. So, the answer is C.
