Answer 1

Estrone and estradiol are the estrogens that control the development of female secondary sex characteristics and the menstrual cycle, both produced in the ovaries.

Step-by-step explanation:

The estrogens estrone and estradiol control the development of secondary sex characteristics, regulate the menstrual cycle, and are made in the ovaries. Therefore, the correct answer is b) Estrone, estradiol.

Estrogens are responsible for features such as breast development, distribution of body fat to the buttocks and thighs, and growth of the uterine lining. Progesterone, on the other hand, prepares the uterus for pregnancy and is also involved in the menstrual cycle but is not classified as an estrogen.
