Solution

The correct option is D Bakelite
Bakelite is a thermosetting plastic, which means it retains its shape even at high temperatures. Whereas, the others mentioned are thermoplastics that can be moulded on heating.

Also, bakelite is a poor conductor of electricity, hence, it protects us from getting electric shocks.

This is the reason, bakelite is used for making electrical switches, handles of various utensils, etc.
