Option 4: phosphorus
Correct Answer: sulphur
Solution : The correct option is sulphur .
By adding sulphur, a chemical process known as vulcanisation transforms rubber or other similar polymers into stronger materials. Through the creation of crosslinks (bridges) between different polymer chains, these additives alter the polymer. Materials that have been vulcanised are less sticky and have better mechanical qualities.
