this obviously is not true and passage does not suggest this in any way
B – Wrong
There is some relevance between this option and the passage, but the reason why this is not the conclusion is because it just says experimentation. It does not specify which type of experimentation.
C – Wrong
This, again, is incorrect as the passage does not justify all experimentation.
D – Correct
This is correct, reason being that the passage says that “those experiments are morally acceptable”. This phrase was used after the passage said that antibiotics help animal too. So, this is correct.
E – Wrong
The passage does not say anything about non-medical research so this option is irrelevant
