Explanation:

Step1: Identify aromatic rings

Aromatic rings follow Huckel's rule and have delocalized pi - electrons. In the clonazepam structure, there are two benzene - like aromatic rings. One is the ring with the nitro ($NO_2$) group and the other is the ring with the chlorine ($Cl$) group. Hydrocarbons are compounds composed of only carbon and hydrogen. Aromatic hydrocarbons in this context refer to the aromatic rings in the molecule. So there are 2 aromatic hydrocarbons in the molecule.
