- 250˚
- 105˚.
- 150˚
- 165˚

Option 2 : 105˚.

The angle between hour hand and the minute hand when the clock shows 9:30 am can be calculated by using the following formula:

Angle = \(\frac{{11}}{2} \times M - 30 \times H\)

Where, M = Minutes and H = Hours

Here M = 30 and H = 9

Therefore, we get angle =| \(\frac{{11}}{2} \times 30 - 30 \times 9\) |= |165 – 270 |= |-105 | =105˚

Hence, 105˚ is the correct answer.
