(B) The thermal stability of the hydrides of group $15$ elements decreases down the group as $NH_{3} > PH_{3} > AsH_{3} > SbH_{3} > BiH_{3}$.As we move down the group,the atomic size of the central atom increases (from $N$ to $Bi$).This leads to an increase in the bond length and a decrease in the bond dissociation enthalpy (bond strength).Consequently,the thermal stability decreases.
