B) young children

Documentaries are one avenue for education, which is suitable for young minds. Also, it's important they understand what the world may be like later down the road when they get older. Unfortunately the process of climate change is something we all have to deal with young or old. The younger generation will be more effected because the older generations will die off by that time in the later future.

One could argue that adults are a good audience as well. This is because adults would have a more serious mindset. Though I think they may not see it as important if the documentary is talking about some far off date in the future. It will depend on the person of course. Not everyone is the same.

We can definitely rule out choices A and C because global warming effects everyone, and not just women or principals.
