(C) The correct order is $NH_3 > PH_3 > AsH_3 > SbH_3$.As we move down the group,the atomic size of the central atom increases.This leads to the dispersion of the lone pair over a larger volume,which decreases the electron density on the central atom.Consequently,the availability of the lone pair for donation decreases,and the basic character decreases.
