The Correct Option is B

Step 1: Understanding Soil Conservation.
Soil conservation refers to the protection of soil from erosion and degradation. It involves adopting methods that maintain soil fertility and prevent loss of topsoil.

Step 2: Role of Afforestation.
Afforestation means planting trees on barren land. Trees hold the soil firmly with their roots, prevent soil erosion by wind and water, and improve soil fertility.

Step 3: Analysis of the options.

• 
  (A) Overgrazing: Incorrect. It removes vegetation cover and increases soil erosion.
• 
  (B) Afforestation: Correct. It protects and conserves soil.
• 
  (C) Mining: Incorrect. It disturbs the land surface and damages soil.
• 
  (D) Soil erosion: Incorrect. It is the loss of soil, not a conservation method.

Step 4: Conclusion.
Thus, afforestation is a method that helps to conserve soil.

Final Answer:} Afforestation.
