Based on the information, which action would reduce the destruction of the ozone layer?

Earth’s atmosphere contains naturally-occurring ozone. Ozone, which contains three

oxygen atoms joined together (O3), forms a layer miles above Earth’s surface. The layer serves as a shield from the harmful ultraviolet rays of the Sun.

A group of chemicals called CFCs (chlorofluorocarbons) are used as refrigerants, propellants, and cleaning solvents. At Earth’s surface CFCs are chemically stable. However, CFC molecules can be broken apart high in the atmosphere and they can destroy the protective ozone layer.

Based on the information, which action would reduce the destruction of the ozone layer?
A . Limit the production and use of CFCs.
B . Use ultraviolet sunscreen more frequently.
C . Plant more oxygen-producing trees.
D . Build many ozone-producing plants.
E . Research ways to convert more ozone into oxygen.
