Verified Answer
A. Only one
B. Only two
C. All the three
D. None
Explanation:
Cigarette butts: The filters are made of cellulose acetate, a type of plastic. Eyeglass lenses: Most modern eyeglass lenses are made from various types of plastic, such as polycarbonate or CR-39. Car tyres: Tyres are composed of a mix of natural and synthetic rubbers, with synthetic rubbers being polymers derived from petroleum, thus a form of plastic. Therefore, all three contain plastic.
