The Correct Option is D

Solution and Explanation

Explanation:
A bicycloalkene cannot have the formula of C2H6.C2H6 has two degree of unsaturation (two H2 less than saturated hydrocarbons), therefore it can be a diene, a cycloalkene or a bicycloalkane but it cannot be a bicycloalkene because it has three degrees of unsaturation.Hence, the correct option is (D).
