Solution

The correct answer is D. Sulfur.

Explanation:

The process of hardening rubber is called vulcanization, and it involves heating rubber with sulfur. The sulfur forms cross-links between the rubber molecules, which makes the rubber harder, more durable, and more resistant to heat and other forms of degradation. This is why sulfur is used to harden the rubber in car tyres.
