Question:

Match List-I with List-II

List-I (Plant Nutrient)List-II (Mobility in Soil / Function in Plant)
(A) Mn(I) Highly mobile
(B) Mg(II) Less mobile
(C) Zn(III) Immobile
(D) C(IV) Basic structure

Choose the correct answer from the options given below.

Show Hint

Always identify the most certain match first. Here, matching Carbon (C) to basic structure (IV) narrows down the options significantly.
  • (A) - (I), (B) - (II), (C) - (III), (D) - (IV)
  • (A) - (I), (B) - (III), (C) - (II), (D) - (IV)
  • (A) - (I), (B) - (II), (C) - (IV), (D) - (III)
  • (A) - (III), (B) - (IV), (C) - (I), (D) - (II)

The Correct Option is A

Solution and Explanation



Step 1: Understanding the Concept:

Nutrients have different behaviors in soil depending on their chemical state and interaction with soil colloids.

Step 2: Detailed Explanation:

Carbon (C) represents the basic skeletal structure of the plant, so (D) matches with (IV).
Zinc (Zn) is highly adsorbed in soils and considered relatively immobile, so (C) matches with (III).
Magnesium (Mg) is less mobile in soil compared to highly mobile anions, so (B) matches with (II).
Manganese (Mn) can be highly mobile in its reduced state, so (A) matches with (I).
This gives the correct combination of (A)-(I), (B)-(II), (C)-(III), (D)-(IV).

Step 3: Final Answer:

Hence, option (A) is the correct match.
