b.

A. It is getting thinner, allowing more harmful ultraviolet rays to reach Earth.

Explanation:

The ozone layer is a region of the Earth's stratosphere that absorbs the Sun's ultraviolet radiation. Therefore, the ozone layer acts as a protective shield. However, the ozone layer is getting thinner, and this phenomenon is particularly evident in Antarctica. This means that harmful rays are able to better reach Earth. The main cause of ozone depletion is the release of harmful chemicals into the atmosphere.

its tr3way you already know

the third answer is correct (c).

the laws that regulate the financing of political campaigns seek to guarantee the smoothness of funding so that there is no abuse of electoral economic power and to avoid the capture of future politicians by the donors.

this is because donor agents have their private interests that are not necessarily the same interests of the society that elected politicians must defend.

thus, interest groups should seek their interests within the legality of lobbying practices that are regulated.
