Solution

The correct option is A Sewage
  • A pollutant can be degradable or nondegradable.
  • A degradable pollutant degrades after some time, either automatically or through the agency of microorganisms (e.g., sewage, livestock wastes, market garbage).
  • Biodegradable pollutants are easily disposed off or degraded through natural processes. They can be turned into a resource e.g., compost and manure.
