Match List-I with List-II regarding the chemical nature of plant growth regulators. List-I List-II (A) Indole compounds (I) Abscisic acid (B) Adenine derivatives (II) Gibberellic acid (C) Carotenoid derivatives (III) Indole-3-acetic acid (D) Terpenes (IV) Kinetin Choose the correct answer from the options given below:
Options
- A(A)-(III), (B)-(IV), (C)-(I), (D)-(II)
- B(A)-(III), (B)-(IV), (C)-(II), (D)-(I)
- C(A)-(IV), (B)-(III), (C)-(I), (D)-(II)
- D(A)-(IV), (B)-(I), (C)-(II), (D)-(III)
Correct answer
A. (A)-(III), (B)-(IV), (C)-(I), (D)-(II)
Step-by-step solution
Plant growth regulators have diverse chemical compositions as described in NCERT: Indole compounds: Indole-3-acetic acid (IAA) Adenine derivatives: N6-furfurylamino purine, kinetin Carotenoid derivatives: Abscisic acid (ABA) Terpenes: Gibberellic acid (GA3) Therefore, the correct match is (A)-(III), (B)-(IV), (C)-(I), (D)-(II). Swapping the derivatives of ABA and GA3, or IAA and Kinetin, represents common confusions regarding their chemical origins. Answer: (A)-(III), (B)-(IV), (C)-(I), (D)-(II)
