Step 1: Associate each irrigation term in LIST I with its most relevant counterpart in LIST II.
- A. Infiltration opportunity time: This is the duration water remains on the soil surface, facilitating infiltration. It correlates directly with III. Time of ponding.
- B. Surface irrigation: This encompasses irrigation techniques (e.g., basin, border, furrow) where water flows across the soil surface, primarily by gravity. It is a type of IV. Gravity irrigation.
- C. Check basin irrigation: This method utilizes small, level basins enclosed by bunds, ideal for irrigating orchards or I. Tree crops.
- D. Cropped area irrigated: The total area under cultivation served by a canal system is determined by the total area the system is intended to cover, referred to as the II. Command area.
Step 2: List the identified pairings.
- A \(\rightarrow\) III
- B \(\rightarrow\) IV
- C \(\rightarrow\) I
- D \(\rightarrow\) II
This set of pairings matches option (C).
