Hi there!
The most important thing to note here is that eukaryotic cells have nuclei. This is the circular blob-like organelle which encases the DNA. Some other differences eukaryotic cells have over prokaryotic cells include more complicated organelles which are membrane bound.
If we look at these images, what we are looking for is a nuclei, as this will appear most evident. When we look at A and B, we can see a circular organelle that is extremely prominent. However, with C and D, that does not appear. C specifically, the nucleic code is exposed and not membrane bound, meaning it is not prokaryotic. D does not appear to contain a nucleus or any genetic material.
Thus, your answer is A and B.
Hope this helps!
