Coronavirus/Pollution

Explanation:

I think the biggest problem for our generation (like right now) is Coronavirus, it has made a big problem for everybody because we can't go out unless we wear our masks and we have to social distance. But if you need generation wise I would say pollution because it has really been affecting us lately and that is one of the reasons why global warming is much much.

Hope this helps :)

the answer would be b.
