Correct answer: D

To find the angle between the hour hand and the minute hand at 10 minutes to 7 (which is 6:50), we can use the relative positions of the hands on the clock face.

Step-by-Step Analysis
Understand the Time: 10 minutes to 7 is 6:50.

Calculate the position of the minute hand:

The minute hand points at 10, which represents 50 minutes.

Since each minute mark is 6 degrees (360 degrees / 60 minutes), the minute hand is at 50 * 6 = 300 degrees from the 12 o'clock position.

Calculate the position of the hour hand:

The hour hand moves 30 degrees per hour (360 degrees / 12 hours) and 0.5 degrees per minute (30 degrees / 60 minutes).

At 6:50, the hour hand has moved past the 6 o'clock position.

Position = (6 hours * 30 degrees) + (50 minutes * 0.5 degrees) = 180 + 25 = 205 degrees from the 12 o'clock position.

Calculate the angle between them:

The difference = |300 degrees - 205 degrees| = 95 degrees.
