what are insulated foam cups most likely made out of?\n○ polyethylene\n○ polystyrene\n○ nylon thread\n○ vulcanized rubber

Answer

Answer:

B. polystyrene

Brief Explanations:

Insulated foam cups are commonly made of polystyrene due to its good insulating properties. Polyethylene is not the typical material for such cups. Nylon thread is for sewing - related uses and vulcanized rubber is used for different industrial and rubber - product applications, not for making foam cups.
