I think I'd go for D on this one. There has to be some link between the two diseases in order to firmly establish that indeed Alzheimer is caused by a virus.

Only option D looks to be in favor of the hypothesis.
Other options seem to doubt it.

scientists are looking for a cause to alzheimers. however when they inject rats with blood of humans another disease is triggered, CK. After that experiment, for the conclusion that alzheimer's is cause by a virus to be valid, we need evidence that binds these two different outcomes with the same cause.
D provides this.

Answer D seems to be logical one out of other answer choices
