The option "development of ovaries in girls and testes in boys" is incorrect as these sex organs start to develop during the teen years.

The secondary sex characteristic that does not typically develop during the teen years is the development of ovaries in girls and testes in boys.

The secondary sex characteristics that do not develop during the teen years are the development of ovaries in girls and testes in boys.

To determine the correct answer, we need to understand what secondary sex characteristics are and when they typically develop. Secondary sex characteristics are physical changes that occur during puberty and differentiate males from females. These changes include the development of breasts in girls, body hair in boys, and the presence of acne.

During the teen years, it is common for girls to experience the development of breasts. This is a result of hormonal changes in their bodies. Similarly, boys may observe the growth of body hair, as well as the presence of acne due to increased oil production and hormonal changes.

However, the development of ovaries in girls and testes in boys actually occurs before the teen years. The ovaries and testes are primary reproductive organs and they develop during fetal development, not during puberty.

Therefore, the correct answer is the development of ovaries in girls and testes in boys.
