The correct answer to this question is B, Oval Fat Bodies. These bodies are tubular epithelial cells, which are degenerating. These oval fat bodies are filled, containing fat droplets. The fats come from leaking tubular cells, which happens through abnormal glomeruli. Appearing in various sizes, oval fat bodies look like clusters of grapes and are found with free floating droplets of fat.
Under a microscope, they display a Maltese cross configuration. This happens because the liquid, crystalized struction gives the oval fat bodies a double refraction. They can be detected in urine when the sediment is stained with Sudan III or Oil Red O stains.
