Answer 1

Answer: (A), (B)

The correct options are
A Thin ozone layer allows more UV radiation to the Earth's surface.

B Increased UV radiations cause skin cancer

Increased usage of CFCs and other halocarbons cause the ozone layer depletion in many parts of the world, including Australia. Due to thinning of ozone, more UV rays penetrate into the atmosphere which are harmful for human health. The increased UV exposure causes skin burn, skin cancer, cataract etc.
