Which is an important consideration that a teen should think about before agreeing to have sex?

The menstrual cycle fact in B and the cost and function of condoms in C may be relevant information, but neither addresses the broad personal and health risks as directly as A. D is not a good reason to have sex; it should be a voluntary, informed decision.
