Manganese is required in 

  • nucleic acid synthesis

  • plant cell wall formation

  • photolysis of water during photosynthesis

  • chlorophyll synthesis

Answer

C.

photolysis of water during photosynthesis

In plants, manganese is absorbed in the form of manganous ions (Mn2+). It activates many enzymes involved in photosynthesis, respiration and nitrogen metabolism. The best-defined function of manganese is in the splitting of water to liberate oxygen during photosynthesis, ie, photolysis of water.
