Solution
The correct option is A Cu, Mn, Fe
Copper is absorbed as cupric ions (Cu2+) from the soil. It is an important constituent of plastocyanin which takes part in electron transport during photosynthetic phosphorylation.
Manganese is absorbed by the plants as manganous ions( Mg2+). It participates in the photolysis of water during non-cyclic photophosphorylation of photosynthesis.
Iron is mainly available in the ferrous form (Fe2+) and it is absorbed in the ferric form (Fe3+). It is a part of proteins like ferrodoxin and cytochromes that are involved in electron transport during photosynthesis.
