(D) The North American Echinacea flower has a derivative which has been effective in preventing colds, that

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
