let's understand the meaning
a derivative of NAEF has been effective in preventing colds
NAEF is grown by many small farmers

Derivative cannot be grown. Because of this, A, B, and C can be eliminated.

in D -> comma+that - i don't like it, furthermore it refers to cold and not flower.
E it is then!

I went with C..
I guess E changes the meaning of the original sentence.
Here, it says that NAEF is grown by many small farmers out West whereas the original sentence states that the derivative(another form of NAEF which has been effective in preventing colds) is grown by many small farmers out West
