Question

Match List - I with List - II.

Choose the correct answer from the options given below :

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

Hint:

Nutrient Toxicity Markers: - Iron toxicity = Bronzing in Rice. - Chloride toxicity = Leaf tip burning margin scorching. - Copper toxicity = Severe root inhibition and stunting.

Answer 1

The Correct Option is D

Step 1: Understanding the Question:
The question requires matching plant nutrients in List - I with their characteristic toxicity symptoms described in List - II.

Step 2: Detailed Nutrient Toxicity Alysis:

• A. Phosphorous Toxicity: Excessive phosphorus causes severe metabolic imbalances, inducing micronutrient deficiencies and leading to leaf tip dieback and necrosis $\rightarrow$ III.
• B. Iron Toxicity: Common in waterlogged/acidic paddy soils; excessive $Fe^{2+}$ causes distinct brownish patches or "bronzing" of older lower leaves $\rightarrow$ I.
• C. Chlorine Toxicity: High chloride accumulation causes margil burning and leaf tip scorching ("burning of leaf tip") $\rightarrow$ II.
• D. Copper Toxicity: Excess Cu restricts root expansion and causes severe plant stunting $\rightarrow$ IV.

Step 3: Verification of Combition:

• A $\rightarrow$ III
• B $\rightarrow$ I
• C $\rightarrow$ II
• D $\rightarrow$ IV
• Matches option (D): A-III, B-I, C-II, D-IV.

Step 4: Fil Answer:
The correct matching is A-III, B-I, C-II, D-IV, corresponding to option (D).
