What is the angle traced by the hour hand in 23 minutes?

Correct option is A

The angle of the hour hand are given below as - 

12 hours = $$360\degree$$

1 hour = $$\frac{360}{12} = 30\degree$$

1 minute = $$\frac{30}{60} = 0.5\degree$$

The angle traced by the hour hand in 23 minutes = $$23 \times 0.5\degree = 11.5\degree$$​​
