Correct option is B)
Angular velocity is defined as the rate of change of angular displacement with respect to time. It is usually expressed by a Greek letter (omega).
Mathematically, angular velocity is ω=dθ/dt If a body is rotating at the rate of N r.p.m. (revolutions per minute), then its angular velocity, ω=602πNrad/s
