The period of a simple pendulum, whose bob is a hollow metallic sphere is T. The period is `T_(1)` when the bob is filled with sand, `T_(2)` when it is filled with mercury and `T_(3)` when it is half-filled with mercury. Which of the following is true?

A

`T = T_1 = T_2 gt T_3`

B

`T_1 = T_1 = T_3 gt T`

C

`T gt T_3 gt T_1 = T_2`

D

`T = T_1 = T_2 lt T_3`
