Solution

The correct option is A Fe and Mg
Chlorophylls have a cyclic tetrapyrrole porphyrin head to which a long phytol tail is attached. The cyclic tetrapyrrole has an atom of magnesium coordinated in the centre. The chlorophyll is synthesized from protochlorophyllide on exposure to light. The synthesis of protochlorophyllide requires iron. Hence, the correct answer is the option B.
