[face=Verdana]Try to think it this way.

(A) does't go against the conclusion, instead, it is against the approach of puting private environment group in charge by saying that it may not serve it purpose, considering part of the group and its leadership may be presided by those against environmental protection.

(C) is irrelevant, in that how the private enviornment group raise money to fund park system has no bearing on their function to serve its purpose. What would happen when they have to seek input from public and donators we really don't know and don't have to bother. If you think their capability is impaired by raising fund from outside, then you commit the fallacy of "take it for granted".

hope helps.[/face]
