Solution
The correct option is D Iron
Iron is an essential micronutrient for plants. It is essential for chlorophyll biosynthesis and also as cofactor for activity of several enzymes, like catalase. Iron is also a component of several proteins used in electron transport system, where it undergoes reversible redox reactions and serve as electron carrier. Ferredoxins are small proteins containing iron and sulfur atoms organized as iron-sulfur clusters. These biological "capacitors" can accept or discharge electrons, the effect being change in the oxidation states of the iron atoms. This way, ferredoxin acts as electron transfer agents in biological redox reactions.
