Menarche typically begins at Tanner stage 2, which usually occurs about 2 to 2.5 years after the onset of breast development in girls. Therefore, the correct answer indicates that menarche usually occurs within a timeframe of around 1 to 2 years after reaching Tanner stage 2. This stage is characterized by the development of breast buds and the onset of pubic hair, marking significant hormonal changes in the body that eventually lead to menstruation.
