Correct Answer - Option 4 : 150°
Clock completes one full rotation i.e., 360º in 12 hours.
So, in 1 hour, the hour hand of a clock moves by 360/12 = 30º
Time gap between 9 O'clock to 2 O'clock = 5 hours
Degrees the hour hand will rotate when the clock shows 2 O'clock in the afternoon = 5 × 30º = 150º
Hence, '150º' is the correct answer.
