Selenium

The correct answer is Option (3)- Selenium

Selenium is a trace mineral found in the human body.

Explanation:

Selenium is an essential trace element that plays a crucial role in various biological functions. It is a component of selenoproteins, which have antioxidant properties and are involved in protecting cells from damage caused by free radicals. Selenium is important for maintaining the health of the immune system, thyroid function, and reproductive system.

While sulfur, magnesium, and phosphorus are important minerals in the body, selenium is specifically classified as a trace mineral due to the relatively lower amounts required compared to major minerals.
