We have an inference question. So let's review what we know:
-Science has a traditional value system (TVS) of its own.
-Scientists sometimes see that their research could do harm, but according to the TVS, they don't have to consider this when deciding whether to keep researching or not.
-Ordinary morality, however, requires that we consider consequences.
(A) is out of scope. There is nothing in the stimulus about responsibility.
(B) is incorrect because the stimulus doesn't actually tell us that doing research that does harm is immoral. It tells us that ordinary morality requires that we consider the consequences--that we at least take them into account. That's different than calling it outright immoral. Maybe we'd consider them and then decide they're not immoral, actually.
(C) is the opposite of what the stimulus tells us; science is not morally neutral.
(D) is correct.
(E) far exceeds the scope of the argument.
Hope this helps!
