The non-metal used in vulcanization of rubber is

Options

A. sulphur
B. carbon
C. phosphorus
D. nitrogen

Explanation

**Step-by-Step Solution:**

1. **Understanding Vulcanization**: Vulcanization is a chemical process that involves heating rubber with sulfur to improve its properties. This process enhances the elasticity, strength, and durability of rubber.

2. **Identifying the Non-Metal Used**: In the process of vulcanization, sulfur is the key non-metal that is used. It reacts with the rubber when heated, forming cross-links between the rubber molecules.

3. **Role of Activators and Accelerators**: During vulcanization, activators and accelerators are also used to enhance the reaction. An example of an activator is zinc fatty acid, and an example of an accelerator is Guanidine. These substances help to speed up the vulcanization process and reduce the amount of sulfur needed.

4. **Conclusion**: The non-metal that is primarily used in the vulcanization of rubber is sulfur.

**Final Answer**: The non-metal used in vulcanization of rubber is sulfur.
