Which category do charities like 'National Trust' and 'Friends of the Earth' fall under?

Okay, let's break down why "Environmental charities" is the right category for organizations like the National Trust and Friends of the Earth. Think about what these groups actually *do*. The National Trust, founded in 1895, is all about preserving historic buildings and areas of natural beauty in the UK. They protect coastlines, forests, historic houses, gardens – all things related to the environment. Friends of the Earth, established much later in 1969, is an advocacy group that campaigns on a range of environmental issues, from climate change to pollution. So, while they might indirectly benefit people or animals, their primary focus is on protecting the natural world. That's why "environmental charities" is the most accurate description. The other options, like medical research, animal, or elderly charities, simply don't align with the core missions of these two organizations.
