Which option is a sanitation facility?

• A. Provision of safe water in sufficient quantity
• B. Building of latrines
• C. Distribution of soap
• D. Appropriate site planning to avoid overcrowding

Answer: (B)

Sanitation facilities are the physical structures that safely manage human waste. Building latrines fits this exactly because a latrine is a designed space for defecation that contains and helps dispose of waste, reducing contamination and disease risk. The other items describe services or activities rather than structures: providing safe water is about water supply, not a waste-management facility; distributing soap is a hygiene supply; and planning to avoid overcrowding is about site and infrastructure planning, not a facility itself. So the best answer is the building of latrines.
