Match List I (Soil Characteristics) with List II (Soil Types):

List I	List II
a. Toxicity of Al & Fe	I. Sodic Soil
b. Amendments with gypsum	II. Saline Soil
c. ECe > 4 ds/m	III. Acid Soil
d. High Calcium Carbonate	IV. Calcareous Soil

Choose the correct answer from the options given below:

Correct option is B

✅ Explanation of Matching:
Acid Soil (III): Commonly exhibits aluminum (Al) and iron (Fe) toxicity, especially at low pH (<5.5). This is detrimental to root growth and nutrient uptake in plants.
Sodic Soil (I): Characterized by excess exchangeable sodium, which degrades soil structure. Gypsum (CaSO₄) is widely used as a soil amendment to displace sodium and improve soil permeability.
Saline Soil (II): Identified by electrical conductivity (ECe) greater than 4 dS/m, indicating a high concentration of soluble salts that can inhibit plant growth.
Calcareous Soil (IV): Contains high levels of calcium carbonate (CaCO₃), making the soil alkaline and affecting the availability of nutrients like phosphorus, zinc, and iron.
