Best answer
The correct choice is (b) PS

For explanation: PS – Polystyrene has very high vapor and gas transmission rate – hence, making it a breathable film. However, it is not suitable for heat sterilization and deteriorates on exposure to sunlight. This film is crystal clear and sparkling, enabling consumers to see through it.
