The conditions necessary for health

• A. Sanitation
• B. Run-off
• C. Sewage
• D. Rock

Answer: (A)

Having good sanitation is a basic condition for health because it prevents disease by safely removing and disposing of human waste, ensuring clean water supplies, and promoting good hygiene. When sanitation measures are in place, the sources of infection are limited and the spread of waterborne illnesses is reduced, supporting overall community health. Run-off is water that can carry pollutants but isn’t itself a necessary health condition. Sewage refers to wastewater that sanitation systems must manage; untreated sewage can harm health, so proper sanitation addresses it but it isn’t the condition that ensures health on its own. Rock has no relevance to health conditions in this context.
