The correct option is B Blue
Wastes that can be decomposed by the action of microbes are called biodegradable wastes. Kitchen wastes like vegetable and fruit peels are considered wet waste and hence, can be separated and kept in green coloured bins for garbage collectors.
Blue dustbins are used for the disposal of plastic materials like wrappers, packing plastics, bottles, cans, etc. These are non-biodegradable wastes.
Yellow dustbins are used for disposing papers and glass bottles. These can be recycled and reused.
Red colour bins are used for disposing of biowaste like bandages, diapers, etc,
So, the correct answer is option B.
