    (A) - (III), (B) - (IV), (C) - (II), (D) - (I)
  • B
    (A) - (II), (B) - (IV), (C) - (I), (D) - (III)
  • C
    (A) - (I), (B) - (II), (C) - (IV), (D) - (III)
  • D
    (A) - (III), (B) - (I), (C) - (IV), (D) - (II)

Solution

Auxins are responsible for apical dominance, which is the phenomenon where the main central stem of the plant is dominant over other side stems.

Gibberellins promote internode elongation just prior to flowering in rosette plants, a process known as bolting.

Ethylene induces epinasty, which is the downward bending of leaves and other plant parts.

Abscisic acid (ABA) acts as a stress hormone and causes the closure of stomata under water stress conditions, thus acting as an antitranspirant.

Therefore, the correct matching is (A) - (III), (B) - (IV), (C) - (II), (D) - (I).

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

Hence, the correct answer is option: 'A'.
