A person exhibiting symptoms of impaired work performance, general fatigue, pale skin, depressed immune function, impaired cognitive and nerve function, and impaired memory is likely suffering from iron-deficiency anemia. pernicious anemia. microcytic anemia. neural tube defects.

The correct option is IRON DEFICIENCY ANAEMIA

Explanation:

Anaemia is a condition that arises when there is not enough haemoglobin available to carry sufficient oxygen from the lungs to supply the needs of the tissues. It occurs when the rate of production of mature cells entering the blood from the reb bone marrow does not keep pace with the rate of haemolysis.. Anaemia can be classified based on:

--> impaired erythrocyte production example, Iron deficiency anaemia. Or

--> increased erythrocyte loss example, haemolytic anaemia.

IRON DEFICIENCY ANAEMIA occurs when the amount of iron nutrient needed in the body system for the production of haemoglobin is decreased. The symptoms includes

- impaired work performance,

- general fatigue,

-pale skin,

- depressed immune function,

- impaired cognitive and nerve function, and impaired memory.
