Answer 2

The least reliable birth control method is the rhythm method. The rhythm method involves tracking the menstrual cycle and avoiding sexual intercourse on days when a woman is most fertile. This method is considered to be unreliable because it does not take into account variations in a woman's cycle, or other factors such as stress or illness that could potentially impact fertility.
