Alina [70]

Answer:

The correct answer is - iron and calcium.

Explanation:

In the teenage years, the body needs more nutrients and the correct amount of vitamins and minerals. Minerals such as iron, calcium, zinc, and iodine for proper growth and development are important for the growth and development of the bodies.
