Plant geneticists continue to modify and refine the DNA of agricultural products, altering genes that affect the abundance and taste of the crop. Eventually, the entire genome of every major food crop will be subject to such manipulation. Once these scientists have mastered the DNA of all major food crops, no obstacles to abundant, delicious vegetables and grains will remain.

The argument to the left is based on which of the following assumptions?

A. All obstacles to agricultural production are susceptible to genetic remedies.
B.Obstacles to the agricultural production are susceptible only to genetic remedies.
C.
D.
E.

[spoiler]Why is OA A and why not B?[/spoiler]

Actually i thought B was the answer because the last sentence talks about the obstacles about taste and quantity. Why do we induce "all" based on just 2 obstacles? May be therey are some other obstacles that is not mentioned!

Could someone elaborate?
