Question

Match the element with its associated functions/roles and choose the correct option among given below
$\begin{array}{cc}Column-I& Column-II\\ \text{A.Boron}& \text{i. Splitting of}{H}_{2}O\text{to liberate}{O}_2\text{during photosynthesis}\\ \text{B. Manganese}& \text{ii. Needed for synthesis of auxins}\\ \text{C.Molybdenum}& \text{iii. Component of nitrogenase}\\ \text{D.Zinc}& \text{iv. Pollen germination}\\ \text{E.Iron}& \text{v. Component of ferredoxin}\end{array}$

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

Answer 1

The correct option is B

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

Boron - Pollen germination
Manganese - splitting of $H_{2}O$ to liberate $O_2$ during photosynthesis
Molybdenum - component of nitrogenase
Zinc - needed for synthesis of auxins
Iron - component of ferredoxin
