- A A-III, B-I, C-IV, D-II
- B A-IV, B-III, C-II, D-I
- C A-IV, B-I, C-III, D-II
- D A-I, B-II, C-IV, D-III
Answer & Solution
Correct Answer
(A) A-III, B-I, C-IV, D-II
Step-by-step Solution
Detailed explanation
(A) A-III, B-I, C-IV, D-II
2,4-D is a synthetic auxin widely used as a herbicide to kill broad-leaved dicot weeds.
\(GA _3\) (Gibberellic acid) is used to speed up the malting process in the brewing industry.
Kinetin is a cytokinin that promotes nutrient mobilisation, which helps in the delay of leaf senescence.
ABA (Abscisic acid) acts as a stress hormone and stimulates the closure of stomata under conditions of water stress.
Therefore, the correct matching is A-III, B-I, C-IV, D-II.
