Identify correct statement among the following

A

The greater the mass of a pendulum bob, the shorter is its frequency of oscillation

B

A simple pendulum with a bob of mass M swings with an angular amplitude of ${40^o}$. When its angular amplitude is ${20^o}$, the tension in the string is less than $Mg\cos {20^o}$.

C

As the length of a simple pendulum is increased, the maximum velocity of its bob during its oscillation will also decreases

D

The fractional change in the time period of a pendulum on changing the temperature is independent of the length of the pendulum
