Best answer
Correct choice is (b) Sulphur

Explanation: In the vulcanisation process, the raw rubber is heated with sulphur. It is a chemical process for converting natural rubber or related polymers into more durable materials via the addition of sulphur or other equivalent curatives or accelerators. These additives modify the polymer by forming cross-links (bridges) between individual polymer chains.
