The correct option is (c) PVC

Explanation: PVC- Polyvinyl Chloride is used as a shrink film for CDs and DVDs (and also Blu-ray discs). PVC shrink films have high strength with good clarity and gloss. Its major use is in shrink wrapping CDs, DVDs and discs, but is also used for shrink wrapping of books, toys and food items.
