| A. Boron | i. splitting of H2O to liberate O2 during photosynthesis |
| B. Manganese | ii. needed for the synthesis of auxins |
| C. Molybdenum | iii. component of nitrogenase |
| D. Zinc E. Iron | iv. Pollen germination v. component of ferredoxin |
<br>Options</br><br>a. A-i, B-ii, C-iii, D-iv, E-v</br><br>b. A-iv, B-i, C-iii, D-ii, E-v</br><br>c. A-iii, B-ii, C-iv, D-v, E-i</br><br>d. A-ii, B-iii, C-v, D-i, E-iv</br>
Solution: The function of the following elements-
- Boron is responsible for germination of pollen grains.
- Manganese is responsible for during photosynthesis, H2O is split to release O2.
- Molybdenum is responsible for the nitrogenase component
- Zinc is the element responsible for auxin production necessitates the presence of this amino acid.
- Ferredoxin’s is the component of Iron.
So, the correct answer is (b) A−(iv), B−(i), C−(iii), D−(ii), E−(v).
