• A. A- (ii), B- (v), C- (iv), D- (i)
• B. A- (iii), B- (iv), C- (ii), D- (i)
• C. A- (iii), B- (v), C- (iv), D- (i)
• D. A- (iii), B- (iv), C- (i), D- (ii)

Answer 1

The correct option is D A- (iii), B- (iv), C- (i), D- (ii)

Chlorophyll is a green pigment present in the green parts of the plant that participates in the photosynthesis. It is a chelating agent that constitutes the magnesium as the central atom.

Nitrate reductases are the molybdoenzymes that converts nitrates into nitrites.

light induced catalytic water splitting during photosynthesis takes place in photosystem-2 complex. This complex is composed of four manganese atoms and one calcium atom.

Boron has a regulatory role in the germiration of pollen grain and pollen tube.
