Answer:

A)

Step-by-step explanation:

0.5 mm is 500micrometers

Just eyeballing the cell there is no way it could be B) or C).

In the circumstances of this question I think the only thing you can really do is look at the cell and try to make an approximate guess on the diameter. In a question like this it can be tricky with A) and D) being so close together in magnitude.

I think it is A). This is because it looks like it would take about 5 of the cell to reach the diameter of the microscope lens.

And 100micrometers is 1/5 of 0.5mm.
