The Correct Option is A
Solution and Explanation
Concept:
Vulcanization is the process of heating natural rubber with sulphur to improve its strength, elasticity, and durability.
Step 1: Raw rubber is soft, sticky, and less durable.
Step 2: During vulcanization, sulphur is added to rubber.
Step 3: Sulphur forms cross-links between polymer chains of rubber.
Step 4: These sulphur cross-links make rubber: \[ \text{stronger, more elastic, and more durable} \] Therefore, the chemical added during vulcanization is: \[ \boxed{\text{Sulphur}} \]
