In vulcanization of rubber :

Asulphur reacts to form a new compound
Bsulphur cross-links are introduced
Correct Answer
Csulphur forms a very thin protective layer over rubber
Dall statements are correct

Solution

Vulcanisation of rubber-
To improve these physical properties,
Strength
Resistance for oxidation
Repulsion from water
a process of vulcanisation is carried out. This process consists of heating a mixture of raw rubber with sulphur and an appropriate additive at a temperature range between $$373 K to 415 K.$$ On vulcanisation, sulphur forms cross links at the reactive sites of double bonds and thus the rubber gets stiffened.
The correct option is [B].
