Verified Solution

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.
