Answer 2

C. A and D

Melamine and Bakelite.

Explanation:

Melamine and Bakelite are both thermosetting plastics. Thermosetting plastics are prepared from low molecular mass semi-fluid substances. Thermosetting plastic can withstand very high temperatures.

Melamine resists fire and can tolerate heat better than other plastics. It is used for making saucepan handles.

Bakelite is a poor conductor of heat and electricity. It is used for making electrical switches, electric plugs and plug boards, etc.

Option C is the answer.
