• A. Naphthalene balls.
• B. Bitumen

Answer 1

The correct option is A

Naphthalene balls.

Bitumen, a petroleum product, is used in place of coal-tar for metalling the roads. It is a very good adhesive. It sticks well to the sub layers. Bitumen is a black, oily, viscous material that is a naturally occurring organic byproduct of decomposed organic materials. The primary use (70%) of asphalt/bitumen is in road construction, where it is used as glue or binder mixed with aggregate particles to create asphalt concrete.
