Answer: A

Explanation

Microbeads are manufactured solid plastic particles of less than one millimeter in their largest dimension. They are most frequently made of polyethylene but can be of other petrochemical plastics such as polypropylene and polystyrene. Microbeads, small pellets of plastic, extensively used in personal care products such as shampoo, baby lotion and face cream and considered toxic to marine life, are being banned internationally.
