Consider the molecules \[\text{C}{{\text{H}}_{\text{4}}}\text{,N}{{\text{H}}_{\text{3}}}\]and \[{{\text{H}}_{\text{2}}}\text{O}\text{.}\]Which of the given statements is false?           

A)  The H -C-H bond angle in \[C{{H}_{4}},\]the H-N- bond angle in \[\text{N}{{\text{H}}_{\text{3}}}\text{,}\]and the H-O-H bond angle in \[{{\text{H}}_{\text{2}}}\text{O}\]ar all greater than \[\text{9}{{\text{0}}^{o}}\]

B)  The H-O-H bond angle in \[{{\text{H}}_{\text{2}}}\text{O}\]is larger than the H-C-H bond angle in \[\text{C}{{\text{H}}_{\text{4}}}.\]

C)  The H-O-H bond angle in \[{{\text{H}}_{\text{2}}}\text{O}\]is smaller than the H-N-H bond angle in \[\text{N}{{\text{H}}_{\text{3}}}\text{.}\]

D)  The H-C-H bond angle in \[\text{C}{{\text{H}}_{4}}\]is larger than the H-N-H bond angle in \[\text{N}{{\text{H}}_{\text{3}}}\text{.}\]
