The farming practice known as Slash and Burn is:

• A. Terrace farming
• B. Slash and Burn
• C. Hydroponics
• D. Urban gardening

Answer: (B)

Slash-and-burn is a shifting cultivation method where farmers clear a plot by slashing vegetation and then burning the debris. The resulting ash adds nutrients to the soil, allowing crops to be grown for a few years before the land loses fertility, at which point the farmer moves on to a new patch. This approach is typically used in tropical regions with low soil fertility and forests nearby, and it differs from terrace farming (which builds steps on hillsides to prevent erosion), hydroponics (growing plants in nutrient solutions without soil), and urban gardening (cultivation in city environments). The described process matches the practice in question.
