A Correct answer
Explanation

Cobalt is an essential component of Vitamin B12 (cobalamin), which is required for red blood cell formation and neurological function. Absence of cobalt (and thus Vitamin B12) leads to pernicious anemia, a condition where the body cannot produce enough healthy red blood cells. This causes fatigue, weakness, and neurological problems. The other options are not related to cobalt deficiency.
