A
to allow UV rays to get to Earth
B
to block UV rays from getting to Earth

Explanation: 

Detailed explanation-1: -The ozone layer in the stratosphere absorbs a portion of the radiation from the sun, preventing it from reaching the planet’s surface. Most importantly, it absorbs the portion of UV light called UVB. UVB is a kind of ultraviolet light from the sun (and sun lamps) that has several harmful effects.

Detailed explanation-2: -The ozone layer is the common term for the high concentration of ozone that is found in the stratosphere around 15–30km above the earth’s surface. It covers the entire planet and protects life on earth by absorbing harmful ultraviolet-B (UV-B) radiation from the sun.

Detailed explanation-3: -The stratospheric ozone layer is Earth’s “sunscreen” – protecting living things from too much ultraviolet radiation from the sun.

Detailed explanation-4: -By absorbing UV-B in the stratosphere, the ozone layer prevents harmful levels of this radiation from reaching Earth’s surface.

Detailed explanation-5: -The ozone layer is present in the lower parts of the stratosphere. It absorbs all the ultraviolet radiations and does not allow them to reach earth’s surface, thus protecting all living organisms from the harmful effects of UV radiations.
