C can be taken out of the question as eukaryotic cells do not have a nucleus. A lysosome is is only in prokaryotic cells so B can be taken out of the question. The answer should be D.
There are so many examples for that in different areas, like TPT1 experiment carried out in our lab recently.Here's one link: http://www.alfa-chemistry.com/tpt1-cas-167218-46-4-item-290583.htm
<span>The labs were unable to reproduce the pharmaceutical company’s data
An important characteristic of scientific experiments is that their results can be replicated. In this case, assuming that the laboratories followed the same procedure as the pharmaceutical company, the fact that the data could not be replicated means that the company's claims are invalid. The validity of the claims is more questionable given the huge difference in the final conclusions, with the company reporting a 35% decrease, while the maximum decrease observed by the labs was 8%.
