| & | Column-I (Mineral) | & | Column-II (Role) |
| a. | K | (i) | Water splitting |
| b. | Zn | (ii) | Energy metabolism |
| c. | Mg | (iii) | Auxin synthesis |
| d. | Mn | (iv) | Stomatal movement |
Options
- Aa(iv), b(iii), c(i), d(ii)
- Ba(iv), b(iii), c(ii), d(i)
- Ca(i), b(ii), c(iii), d(iv)
- Da(i), b(ii), c(iv), d(iii)
Correct answer
B. a(iv), b(iii), c(ii), d(i)
Step-by-step solution
K = Stomatal movement (Potassium is involved in protein synthesis, opening, and closing of stomata); Zn = Auxin synthesis (Zinc is required in the synthesis of auxin); Mg = Energy metabolism (Magnesium activates the enzymes of respiration and photosynthesis); Mn = Water splitting (Splitting of water molecule during photosynthesis is facilitated by manganese).
