Explanation:

Step1: Identify aromatic rings

Aromatic hydrocarbons (arenes) have benzene - like rings. In the Clonazepam structure, we can see two benzene rings (one with $-NO_2$ group and one with $-Cl$ group). These are aromatic rings (aromatic hydrocarbons as they are benzene - based with substituents, but the ring structure is aromatic hydrocarbon - like).

Step2: Count the aromatic rings

By visually inspecting the molecular structure, we can identify that there are 2 aromatic (benzene - type) rings.
