A. Iron B. Magnesium C. Phosphorus D. Potassium

Correct Answer is A

Explanation

A. Iron:
Function: Iron is essential for the formation of hemoglobin, a protein in red blood cells that carries oxygen from the lungs to the rest of the body. It is vital for oxygen transport and overall cellular function.
Relevance: Iron deficiency can lead to anemia, characterized by reduced oxygen-carrying capacity of the blood, resulting in fatigue, weakness, and other symptoms.

B. Magnesium:
Function: Magnesium is involved in various cellular processes, including muscle and nerve function, blood glucose control, and bone health.
Relevance: While magnesium has important functions in the body, it is not directly involved in the transport of oxygen like iron.

C. Phosphorus:

Function: Phosphorus is a key component of DNA, RNA, and ATP, playing a role in energy metabolism, bone health, and acid-base balance.
Relevance: While important for cellular processes, phosphorus is not specifically linked to the transport of oxygen.

D. Potassium:
Function: Potassium is crucial for maintaining proper fluid balance, nerve impulses, and muscle contractions.
Relevance: Potassium is not directly involved in the transport of oxygen; its primary functions are related to electrolyte balance and cellular activities.
