(a)
Interpretation: A synthesis of given compound from benzene, any organic compounds having four carbons or fewer, and any required inorganic reagents is to be stated.
Concept introduction: Cyclopropane can be formed by Smith reaction. The reaction of dihalocarbene with the alkene results in addition of carbene to the alkene and this addition takes place from either side of the plane.
