Within 20 years it will probably be possible to identify the genetic susceptibility an individual may have toward any particular disease. Eventually, effective strategies will be discovered to counteract each such susceptibility. Once these effective strategies are found, therefore, the people who follow them will never get sick.

The argument above is based on which of the following assumptions?

(A) For every disease there is only one strategy that can prevent its occurrence.
(B) In the future, genetics will be the only medical specialty of any importance.
(C) All human sicknesses are in part the result of individuals genetic susceptibilities
(D) All humans are genetically susceptible to some diseases.
(E) People will follow medical advice when they are convinced that it is effective.

What is wrong with option D?

Conclusion: once strategies are found to counteract genetic susceptibility to illness, people who use them won't get sick.
Premise: Within 20 years it will be possible to identify genetic susceptibility to any illness.

D doesn't follow from this argument. Just because people with susceptibilities will have a way to avoid getting sick, doesn't mean that EVERYONE is susceptible.

It's also useful to try negation here. The correct answer, when negated, should undermine he argument.

C negated: NOT all humans sicknesses are in part the result of individuals' genetic susceptibilities. Well, if that's true, we can no longer assume that people will no longer get sick simply because they prevent diseases they're genetically susceptible to. There could be other diseases that these strategies would be useless against. Because C, when negated, undermines the argument, we know it's the correct answer.
