A Correct answer
Explanation

Teflon (polytetrafluoroethylene or PTFE) is the standard non-stick coating used on cookware due to its high heat resistance, chemical inertness, and extremely low friction surface. PVC is used for pipes and insulation, black paint is simply a coloring agent, and polystyrene is a brittle plastic used for packaging - none of these provide non-stick properties.
