Answer 1

The correct option is (a) 2

To explain I would say: The rejected materials which are collected in dustbins and the foul discharges that are carried by underground drains are termed as refuse. It may be dry refuse (grass, paper, cloth, vegetable peels) or wet refuse (urinals, kitchen discharges).
