1. A powder derived from the North American Echinacea flower, which has been effective in preventing colds, is grown by many small farmers out West.

(A) A powder derived from the North American Echinacea flower, which has been effective in preventing colds,
(B) A derivative, which has been effective in preventing colds, of the North American Echinacea flower
(C) A North American Echinacea flower derivative, which has been effective in preventing colds
(D) The North American Echinacea flower has a derivative which has been effective in preventing colds, that
(E) The North American Echinacea flower, a derivative of which has been effective in preventing colds,

This question is a easy one , but I have a silly confusion on aswer choice E.

"Of which " refers to Echinacea flower so Can I ignore this as of which is not close to the noun it modifies ???

What is a scope of the rule "Close of noun " for noun modifiers.

Thanks

Reformatted the question.

(A) A powder derived from the North American Echinacea flower, which has been effective in preventing colds,
"powder" cannot "be grown"
(B) A derivative, which has been effective in preventing colds, of the North American Echinacea flower
The same as A
(C) A North American Echinacea flower derivative, which has been effective in preventing colds
The same as A
(D) The North American Echinacea flower has a derivative which has been effective in preventing colds, that
"that" is ambiguos
(E) The North American Echinacea flower, a derivative of which has been effective in preventing colds,
Correct

The key word here is "is grown". "a derivative powder prevents cold" still makes sense.

Look at the last part "is grown by many farmers out West". So the subject has to be "The North American Echinacea flower". This eliminates A, B and C. D doesn't follow a logical pattern as that cannot be used like this. So E
