Concept:Sustainable sanitation involves long-term solutions that reduce waste and change people’s behaviour, not just temporary clean-ups.
Explanation:Building landfills and incinerators only manage waste, but they can cause pollution and do not reduce waste creation.
Sweeping and collecting waste is good, but it is a repeated activity, not a lasting solution.
Recycling reduces the amount of waste that needs disposal, while education helps people adopt better waste management habits.
This combination addresses the root cause of poor sanitation and can be maintained by the community over time.
Answer:C. Recycling and education
