Explanation:

Let's look into each option:

- Contour Trenching: Involves creating trenches along the contour lines to capture and store rainwater.

- Tied Ridging: Involves creating long, narrow, elevated strips (ridges) with earth bands within furrows, designed to hold water and prevent erosion. 

- Correct Answer: This matches the description provided.

- Compartmental Bunding: Involves dividing the field into compartments to manage water flow and soil erosion.

- BBF (Broad Bed and Furrow): Involves creating wide beds separated by furrows for efficient drainage and cultivation.

- Contour Bunding: Entails creating embankments along the contour for water retention and erosion control.
