This question was cancelled (#) in the official MPSC final answer key.

Key Points:
• Question Cancelled by MPSC (`#` in Final Answer Key):
• Soil Conservation Principles: All four listed techniques represent standard agronomic and mechanical soil conservation methods:
• Vegetative cover / Afforestation (a): Intercepts raindrop impact and anchors soil particles.
• Terracing (b): Reduces slope steepness and runoff velocity in hilly terrain.
• Prohibition of shifting cultivation (c): Prevents slash-and-burn erosion and forest destruction.
• Crop rotation (d): Maintains soil organic structure, cover, and nutrient equilibrium.
• Because all four statements (a, b, c, and d) are universally correct soil conservation practices, the absence of an 'All of the above' option created an ambiguity in the multiple-choice options, leading the Commission to officially cancel this question (`#`).
• Key Takeaway: All listed methods (afforestation, terracing, banning shifting cultivation, crop rotation) conserve soil; question cancelled (#) due to option limits.
