• B. Blocking of drain
• C. Pollution of air

Answer 1

The correct option is D Reuse of old glass jar

Glass is a non biodegradable substance. Glass industries emit gaseous oxides of nitrogen, sulphur, and carbon​ which pollutes the air. If glass materials are not disposed properly it can led to the choking of drainage pipes and death of aquatic life.
Reuse is one of the 4R's that emphasis on reusing empty or old glass jars and bottles to store food, water, and other stuff.
