Consider the molecules $CH_4, NH_3$ and $H_2O$. Which of the given statements is false?

Question

( A ) The $H – O – H$ bond angle in $H_2O$ is smaller than the $H – N – H$ bond angle in $NH_3$
( B ) The $H – O – H$ bond angle in $H_2O$ is larger than the $H – C – H$ bond angle in $CH_4$
( C ) The $H – C – H$ bond angle in $CH_4$, the $H – N – H$ bond angle in $NH_3$, and the $H – O – H$ bond angle in $H_2O$ are all greater than $90^o$
( D ) The $H – C – H$ bond angle in $CH_4$ is larger than the $H – C – H$ bond angle in $NH_3$
