Answer 1

The correct option is B

To avoid water table

Deep well injection is a method by which hazardous wastes like nuclear or radioactive wastes are burried deep into Earth layer in order to avoid the contamination of ground water resources and the top soil along with water tables. These hazardous wastes are not thrown off into deep space as it might cause greater impact on our immediate surroundings as well as it is not cost effective.
