Solution
The correct option is C Mg Magnesium is an essential mineral element. It is one of the macronutrients. It is a part of the ring structure of chlorophyll. A non-ionic magnesium is held in the centre of porphyrin head by nitrogen atoms of pyrrole rings. Mg is also responsible for the maintenance of ribosome structure. Ribosome has two subunits. Mg+ is required for the binding of these two subunits.
