`NH_3` has got pyramidal structure. By replacement of `H` atom it forms `(CH_3)_3 N` and `(SiH_3)_3 N` molecules which are found to have different geometries.
Which is the correct relation of bond angles ?

A

`NH_3 gt (CH_3)_3 N gt (SiH_3)_3 N`

B

`(SiH_3)_3 N gt (CH_3)_3 N gt NH_3`

C

`NH_3 gt (SiH_3)_3 N gt (CH_3)_3 N`

D

`(CH_3)_3 N gt (SiH_3)_3 N gt NH_3`
