Reforestation is the process of restoring tree cover to areas where woodlands or forest once existed.

• A. Deforestation
• B. Reforestation
• C. Afforestation
• D. Desertification

Answer: (B)

The concept here is about restoring forests where they used to exist. Reforestation specifically means bringing back tree cover to areas that previously supported woodlands or forests, so the statement matches that definition exactly. It can involve planting trees or encouraging natural regeneration to rebuild a forest on land that was forest in the past.

To distinguish the other terms: deforestation is the removal or clearing of forests that are already there; afforestation is creating new forest on land that has not been forest before; desertification is the broad process of land degradation that can turn productive land into desert-like conditions. So this description is the best fit for reforestation because it centers on restoring former forested land.
