Answer 2

Answer:

(C) 6,6 Dimethyl cyclohexene

Explanation:

It is incorrect as this molecule cannot exist in nature due to the presence of 5 bonds on the double bonded carbon. Even if it were possible for the molecule to exist, the IUPAC name is incorrect as the numbering is incorrect. The carbon with the methyl groups attached will be numbered 1 and the correct name will be 1,1-Dimethyl cyclohexene.
