Solution

The correct option is C melt the sulphur
In the Frasch process, the sulphur under the ground is in solid form If we pass superheated steam, into one of the pipe and air from other, sulphur melt is produced from other pipes. We use superheated steam because the pipes are depth into the ground and when we make it melt, it can come u easily.
