Solution

The correct option is C

PTEE


PTFE Polytetrafluoroethylene or teflon, as it is commonly called is an extremely resistant polymer. It can also be used for lubrication to reduce wear and tear of machine parts.

These properties can be attributed to the presence of all the fluorine atoms in this compound which are highly non-reactive with other chemical element or compound.
