Question

Match List-I with List-II.

List-I (Plant hormones)	List-II (Major function)
(A) Auxins	(I) Induces leaf and fruit abscission
(B) Cytokinin	(II) Elongation of cells
(C) Abscisic acid	(III) Stimulates the swelling of stems and roots
(D) Ethylene	(IV) Stimulate cell division

Choose the correct answer from the options given below:

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

Hint:

Match each hormone to the one growth process it is most famous for.

Answer 1

The Correct Option is A

Step 1: Understanding the Question:
We need to pair each plant hormone in List-I with its major function in List-II.

Step 2: Key Formula or Approach:
Each of the five classic plant hormones has one function it is best known for: auxin drives cell elongation, cytokinin drives cell division, abscisic acid is the stress hormone that triggers abscission and dormancy, and ethylene is the gas hormone linked with ripening and with thickening or swelling responses in stems and roots.

Step 3: Detailed Explanation:
(A) Auxins are best known for stretching the cell wall and pushing cell elongation, which is function (II).
(B) Cytokinins push the cell cycle forward and drive cell division, which is function (IV).
(C) Abscisic acid builds up under stress and pushes leaves and fruits to detach, so it matches (I), induces leaf and fruit abscission.
(D) Ethylene is behind the classic triple response in seedlings, part of which is the swelling and thickening of stems and roots, matching (III).

Step 4: Final Answer:
The correct matching is (A)-(II), (B)-(IV), (C)-(I), (D)-(III), which is option 1.
