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

• A
  The $H-O-H$ bond angle in $H_2O$ is smaller than the $H-N-H$ bond angle in $NH_3$.
• B
  The $H-C-H$ bond angle in $CH_4$ is larger than the $H-N-H$ bond angle in $NH_3$.
• 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 $90^{\circ}$.
• D
  The $H-O-H$ bond angle in $H_2O$ is larger than the $H-C-H$ bond angle in $CH_4$.
