Which method is most often used to propose amendments to state constitutions?

A. A constitutional convention is held to propose amendments

B. A petition proposes the amendment and begins the initiative process.

C. A new amendment is proposed in a session of the legislature.

D. A governor proposes the amendment in a state address.

I have concluded that the answer isn't B or D. So I've narrowed it down to being A or C, but I am not too sure. If anyone could help I would appreciate it.
