(D) The given structure is benzonitrile $(C_6H_5CN)$.Structure analysis:- The benzene ring has $3$ $\pi$ bonds.- The $-CN$ group has a triple bond,which contains $2$ $\pi$ bonds.- Total $\pi$ bonds = $3 + 2 = 5$.Counting $\sigma$ bonds:- Benzene ring $(C_6H_6)$: $6$ $C-C$ $\sigma$ bonds + $5$ $C-H$ $\sigma$ bonds = $11$ $\sigma$ bonds.- Bond between ring and $-CN$ group: $1$ $\sigma$ bond.- $C \equiv N$ group: $1$ $\sigma$ bond.- Total $\sigma$ bonds = $11 + 1 + 1 = 13$.Thus,the number of $\pi$ bonds is $5$ and $\sigma$ bonds is $13$.
