Answer 1

The correct option is A A-iv, B-i, C-iii, D-ii, E-v

Boron - Pollen germination

Pollen germination requires boron.

Manganese - Splitting of $H_{2}O$ to liberate $O_2$ during photosynthesis

Manganese plays an important role in the photolysis during photosynthesis.

Molybdenum - Component of nitrogenase

Molybdenum is a component of the enzyme nitrogenase which help in nitrogen fixation.

Zinc - Needed for synthesis of auxins

Auxin synthesis requires Zn.

Iron - Component of ferredoxin

Iron is a component of ferredoxin which takes part in electron transfer reactions.

Final answer

b.A-iv, B-i, C-iii, D-ii, E-v
