NH ₃ , there are 4 electron pairs (3 bonding pairs and one lone pair) in the outer most shell of N. The repulsion between lone pair and a bond pair of electrons always exceeds that between two bond pairs. Thus the bond angles are reduced from 109⁰27' to 107⁰48'. 

PH ₃ would be expected to be similar. But, the bond pairs of electrons are much further away from the central atom due to its larger size than they are in NH₃. Thus the lone pair causes even greater distortion in PH_3. The bond angle decrease to 91⁰18'

Thus, the bond angle of PH₃ molecule is lesser than that in NH₃ molecule.

correct option is a) much lesser than the NH3
