Options

  1. AA-III, B-I, C-IV, D-II
  2. BA-IV, B-III, C-II, D-I
  3. CA-IV, B-I, C-III, D-II
  4. DA-I, B-II, C-IV, D-III

Correct answer

A. A-III, B-I, C-IV, D-II

Step-by-step solution

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. Answer: A-III, B-I, C-IV, D-II
