A Correct answer
Explanation

At 3 o'clock, the hour hand is at 3 and the minute hand is at 12. The angle between them is 3 * 30 degrees = 90 degrees.

AI explanation

At 3 o'clock, the minute hand points to 12 and the hour hand points to 3. Using the clock angle formula, the angle equals 30 degrees multiplied by the hour minus 5.5 degrees multiplied by the minutes. Substituting the values gives 30 multiplied by 3 minus 5.5 multiplied by 0, which equals 90 degrees. The result is 90 degrees.
