Recycled plastics cannot be used to produce new food containers because a. they are too hard to mold b. they cannot be placed in a freezer c. they cannot be sterilized d. their molecules are too complex

C

Explanation:

Research shows that plastic can absorb chemicals during waste management - after its disposal and before collection. The chemical may be hard to eliminate completely during recycling hence may be a source for contamination of food in food packaging after recycling. The risk for food contamination is definitely higher in second-hand plastic than in pristine plastic.
