• A. 1
• B. 2
• C. 3
• D. 4

Answer 1

The correct option is C 3

Benzene is composed of $6$ carbon atoms and $1$ hydrogen atoms attached to each carbon atom. It contains only carbon and hydrogen atom so it a hydrocarbon. It is a cyclic hydrocarbon with a continuous $\pi$ bond. It has three double bonds in the benzene ring. These are present at the alternate position at carbon number $1,3,5$.
