As the temperature is increased, the time period of a pendulum

A

increases as its effective length increases even though its centre of mass still remains at centre of bob

B

remains same as its centre of mass still remains at centre of the bob

C

increases as its effective length increases due to shifting of its centre of mass below the centre of bob

D

decreases as its effective length remains same but the centre of mass shifts above the centre of the bob
