Answer: c. reproduce
Puberty is the time in the life of humans when we transition from children to adults. This usually means that we develop our sexuality, and become capable of reproducing. Therefore, teenagers are often advised to be careful when engaging in sexual relations so that their relationship does not lead to an unwanted pregnancy. It is also important for them to know that physical maturity does not equal psychological maturity, and that most people are not ready to face the responsibilities of being a parent at that age.
