Question

Match the following: 

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

Hint:

Kinetin is derived from adenine, abscisic acid is derived from carotenoids, naphthaleneacetic acid is a synthetic auxin, and ethylene is the respiratory climactic agent.

Answer 1

The Correct Option is D

Let’s match the correct hormones and their corresponding derivatives:
- A) Adenine derivatives are associated with Kinetin (II), a plant hormone involved in promoting cell division and shoot initiation.
- B) Carotenoids derivatives are associated with Abscisic acid (I), a plant hormone that regulates growth, helps plants respond to stress, and controls seed dormancy.
- C) Synthetic auxin is commonly associated with Napthaleneacetic acid (IV), a synthetic plant growth regulator that acts like the natural auxins.
- D) Respiratory climactic is linked with Ethylene (III), a plant hormone that is involved in regulating the ripening of fruit and other aspects of plant growth. Thus, the correct matching is:
- A) Adenine derivatives → Kinetin (II)
- B) Carotenoids derivatives → Abscisic acid (I)
- C) Synthetic auxin → Napthaleneacetic acid (IV)
- D) Respiratory climactic → Ethylene (III) Hence, the correct answer is (4) A-II, B-I, C-IV, D-III.
