(D) Benzene $(C_6H_6)$ consists of a hexagonal ring of six carbon atoms,each bonded to one hydrogen atom.There are $6$ $C-C$ bonds and $6$ $C-H$ bonds.In the ring,there are $3$ double bonds and $3$ single bonds.Each single bond is a $\sigma$ bond,and each double bond consists of one $\sigma$ bond and one $\pi$ bond.Total $\sigma$ bonds = $6$ ($C-C$ $\sigma$ bonds) + $6$ ($C-H$ $\sigma$ bonds) = $12$ $\sigma$ bonds.Total $\pi$ bonds = $3$ $\pi$ bonds.Thus,benzene contains $12$ $\sigma$ bonds and $3$ $\pi$ bonds.

The number of sigma $(\sigma)$ and pi $(\pi)$ bonds present in benzene respectively are:
