Question

Match List I with List II

Choose the correct answer from the options given below:

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

Hint:

Vertical drainage $\rightarrow$ Tube wells; Subsurface $\rightarrow$ Pipe drainage; Mole drainage $\rightarrow$ Pipeless drainage; Bio-drainage $\rightarrow$ Trees.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Classification of agricultural drainage systems according to physical mechanisms, conduit materials, and biological extraction methods.

Step 2: Detailed Explanation:
Matching the drainage systems in List I with their descriptions in List II:
- A. Vertical drainage: Achieved by pumping groundwater from a battery of drainage tube wells (IV) to lower deep regional water tables.
- B. Subsurface drainage: Conventional horizontal pipe drainage (I) using buried perforated corrugated plastic or clay pipes.
- C. Mole drainage: Pipeless drainage (II) formed by pulling a bullet-nosed cylindrical mole plow through dense cohesive clay subsoils without installing pipes.
- D. Bio-drainage: Biological drainage by high-transpiring deep-rooted trees (III).
Matching sequence: A-IV, B-I, C-II, D-III.

Step 3: Final Answer:
Hence, the correct matching is A-IV, B-I, C-II, D-III, corresponding to option (A).
