{'deficiency': [5, 0, 10, 2], 'calcium': [2, 0, 0, 4], 'minerals': [1, 0, 2, 6], 'zinc': [1, 0, 0, 2], 'immunodeficiency': [0, 0, 1, 0], 'copper': [1, 0, 1, 1], 'lead': [7, 1, 11, 11]}

Option 1: Calcium

Calcium is not directly involved in immune function, so a deficiency of calcium is unlikely to lead to an immunodeficiency. Calcium is mainly responsible for maintaining strong bones and teeth, muscle function, and nerve transmission in the body.

Option 2: Zinc

Zinc is an essential mineral that plays a crucial role in the functioning of the immune system. It is involved in various immune functions, including the development and activation of immune cells, production of antibodies, and regulation of inflammation. A deficiency of zinc can weaken the immune system and increase the risk of infections, making it a more likely cause of immunodeficiency.

Option 3: Lead

Lead is a toxic metal and its presence in the body can have detrimental effects on multiple systems, including the immune system. However, a deficiency of lead would not lead to immunodeficiency. In fact, excessive exposure to lead can impair immune function and increase the susceptibility to infections.

Option 4: Copper

Copper is another essential mineral that plays a role in immune function. It is involved in the development and activation of immune cells, antioxidant defense, and the production of collagen. However, a deficiency of copper is less likely to lead to immunodeficiency compared to a deficiency of zinc.
