Solution

  List - I   List - II
(a) Manganese (iv)

Functions in splitting of water during photosynthesis. During photolysis of water, mediated by PS-II, Mn, Cl, etc. help in breaking the water molecule and release of electron, proton, etc.
(b) Magnesium (iii)

Activates enzymes of respiration. The enzyme needed to convert glucose to glucose-6-phosphate needs the co-factor Mg+2.
(c) Boron (ii)

Required for pollen germination. The stigmatic surface provides complex sugar solution along with Boron which germinates the pollen on stigma. 
(d) Iron (i) Activates the enzyme catalase. Several enzymes like catalase and cytochrome, need cofactors like Fe, for their functioning.

Hence, the correct answer is option: 'A'.
