B Correct answer
Explanation

Manganese is a trace element present in very small quantities in the human body (10-20 mg), unlike sodium and potassium which are macrominerals present in much larger amounts (100-140 g). Aluminium is not considered essential for human life. Trace elements like manganese are required in minute quantities for proper enzyme function.
