Which of the following arrangements correctly represent a decreasing order of bond angles?

$\begin{array}{1 1}(a)\;NH_3 > PH_3 > AsH_3\\ (b)\;NH_3 > H_2O > F_2O \\(c)\;CH_4 > NH_3 > H_2O\\(d)\;\text{None of these}\end{array} $

Can you answer this question?

Due to the increasing size and decreasing electronegativity of the central atom,the bonding electrons are drawn out further,thus repulsion between bonding pairs of electrons decreased.
Hence (a) $NH_3 > PH_3 > AsH_3$ is the correct answer.
