Q.
Match List-I with List-II
| List-I (Growth Regulator) | List-II (Function/Effect) | ||
|---|---|---|---|
| A. | 2,4-D | I. | Brewing industry |
| B. | GA | II. | Stimulation of stomatal closure |
| C. | Kinetin | III. | Herbicide |
| D. | ABA | IV. | Nutrient mobilisation |
Choose the correct answer from the options given below :
- A
A-III, B-I, C-IV, D-II
- B
A-IV, B-III, C-II, D-I
- C
A-I, B-IV, C-III, D-II
- D
A-I, B-II, C-IV, D-III
Solution
2,4-D (an auxin) is used as a selective herbicide.
GA (Gibberellic acid) is used in the brewing industry to speed up malting.
Kinetin (a cytokinin) helps in nutrient mobilisation.
ABA (Abscisic acid) stimulates stomatal closure.
