(A) The electronic configuration of Phosphorus $(Z = 15)$ is $1s^2 2s^2 2p^6 3s^2 3p^3$. According to Hund's rule of maximum multiplicity,pairing of electrons in the orbitals of a particular subshell $(p, d, f)$ does not take place until each orbital of that subshell is singly occupied. Since the $3p$ subshell has $3$ orbitals,the $3$ electrons in the $3p$ subshell occupy these orbitals singly,resulting in $3$ unpaired electrons.
