The method of contraception that is not recommended for teens is g) All of the above.

Here's why:

a) Fertility awareness: This method requires a deep understanding of one's menstrual cycle and can be unreliable, especially for teens whose cycles may not be regular yet.

b) Sterilization: This is a permanent method of contraception and is not recommended for teens who may want to have children in the future.

c) Withdrawal: This method is not reliable as it requires a lot of self-control and even then, there is a risk of pre-ejaculation.

d) Douching: This method is not effective at preventing pregnancy and can actually increase the risk of infection.

e) Having sex in certain positions: There is no scientific evidence to support the idea that certain positions can prevent pregnancy.

Therefore, all of these methods are not recommended for teens. It's important for teens to have access to reliable and safe methods of contraception, along with the education to use them correctly.
