Cannot agree that A at first glance gives it out. But make sure you go through other choices as a routine there could be some thing better hiding.

Assumption question do the negation test.actually b talks only remedy is genetics. Say there is any other remedy other than genetics then ->is it hampering my conclusion - no. but in a say not all are covered under genetics then is it hampering the conclusion. yes. so A is correct.

Also for negation please do check

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
There is already a visible change in produce size at supermarkets, attributable to genetic manipulation of crops.
D
Produce taste tests should be conducted to compare genetically modified produce and natural produce.
E
Consumers have grown increasingly skeptical of the merits of genetically modified produce.

I don't think taht we should even discuss about CDE.
A and B are contender.
Lets try B first.
B says-Obstacles to the agricultural production are susceptible only to genetic remedies. On negating, we come up with "Obstacles to the agricultural production are susceptible NOT only to genetic remedies". It implies that that there are other remedies also; consider that the other remedy be X.
Now if I say that obstacles to the agricultural production are susceptible to genetic remedies and X then how can we conclude that once these scientists have mastered the DNA, there would be no obstacles. May be that some obstacles are susceptible to only X.

Now try A-All obstacles to agricultural production are susceptible to genetic remedies.
The argument says that "once these scientists have mastered the DNA, there would be NO obstacles". So it is clear that A is the assumption here.
+1A

the explanation provided by Marcab is convincing
to too go for A

Talks about no obstacles will remain. Assumption is that all obstacles can be remedied.

B is clearly wrong. Coz it says ....only remedy is genetics. Not true. May have other remedies.

b is clearly wrong because it says that obstacles..it should be all obstacles..
