(D) The central atom in $NH_3$ is nitrogen $(N)$,which has $5$ valence electrons.It forms $3$ covalent bonds with $3$ hydrogen atoms and retains $1$ lone pair of electrons.According to $VSEPR$ theory,the presence of $1$ lone pair and $3$ bond pairs results in $sp^3$ hybridization with a distorted tetrahedral geometry.Due to the lone pair-bond pair repulsion,the bond angle is reduced from $109.5^{\circ}$ to $107^{\circ}$,resulting in a pyramidal shape.

The shape of a molecule of $NH_3$,in which the central atom contains a lone pair of electrons,is
