Solution

The correct option is A sulphur
The nonmetal used to treat rubber in the process of vulcanization is sulphur.
Natural rubber is soft, sticky and has less tensile strength. Vulcanization makes rubber more strong, tough and elastic. Natural rubber is mixed with 3-5% sulphur and heated at 373 K to 415 K. On vulcanisation, sulphur forms cross links at the reactive sites of double bonds and thus the rubber gets stiffened.

The probable structures of vulcanised rubber molecules are depicted below:
