Solution

The correct option is B vulcanisation
Natural rubber is obtained from the sap of rubber trees. It is soft and elastic.

In order to make the rubber stronger, and more flexible, it is heated with sulphur for few hours. This process is called vulcanisation. Vulcanised rubber is more resistant to heat, and other environmental conditions.
