A is completely irrelevant and argument doesnt make that assumption

I chose B but its wrong since argument says that fertilizer use will be reduced, it doesnt say we dont have to use fertlizers anymore. If it had said that we dont need fertilizer then it would have been correct.

C is also attractive but it doesnt set the conncection between why the need for fertilizer will be reduced

D isnt relevant

E is correct because if E wasnt true then there would be no argument.
