Among the following the correct statement is

(a) Between $NH_3$ and $PH_3$, $NH_3$ is a better electron donor because the lone pair of electrons occupies spherical 's' orbital and is less directional
(b) Between $NH_3$ and $PH_3$, $PH_3$ is a better electron donor because the lone pair of electrons occupies spherical $sp^3$ orbital and is more directional
(c) Between $NH_3$ and $PH_3$, $NH_3$ is a better electron donor because the lone pair of electrons occupies spherical $sp^3$ orbital and is more directional
(d) Between $NH_3$ and $PH_3$, $PH_3$ is a better electron donor because the lone pair of electrons occupies spherical 's' orbital and is less directional
