Which element would be considered a trace element? a) carbon b) hydrogen c) iron d) nitrogen

Your answer is C if its asking for trace in the human body and if its asking for normal trace such as (DNA) it would be A .

Brainiest Please?

The option C is correct. Iron is a trace element.

Trace elements are elements which are required in small amounts but they are essential to the body.

Carbon and hydrogen are needed in abundant amount because it is present in all organic compounds like sugars, and lipids.

Nitrogen is part of amino acids, building blocks of proteins.

Iron is essential only for some enzymes and hemoglobin. And it can also be recycled in the body.
