Correct answer
ABoth Statement I and Statement II are correct.

Step-by-step explanation

The -bond present is alkenes is weaker than bond present in alkanes. That makes alkenes less stable than alkanes. Therefore, statement-I is correct.

Carbon-carbon double bond is stronger than Carbon-carbon single bond because more energy is required to break 1 sigma and 1 pi bond than to break 1 sigma bond only. Therefore, statement-II is also correct.
