Solution

The correct option is B are cheap
Plastics are widely used because they are light, cheap, non-reactive and strong. They are also poor conductors of heat and electricity which make them a popular choice for making electrical switchboards, handles of frying pans, etc.

However, they are non-biodegradable and hence, are not eco-friendly.
