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
