Choose the crystal that represents cholesterol crystal.

Explanation:
Cholesterol crystals in urine have a distinctive flat, plate-like shape with notched corners, often yellow and easily seen as refractile under polarized light. This appearance is characteristic of lipiduria, such as in nephrotic syndrome, where excess lipids are excreted into urine and can crystallize as these flat, rectangular plates. The other crystals have different morphologies: leucine crystals tend to be oily, sometimes in a rosette or sheaf-like form; ammonium biurate crystals are brown, thorny spheres; and triple phosphate crystals are colorless prisms with a coffin-lid shape, typically in alkaline urine. So the crystal with flat, rectangular plates and notched edges best represents cholesterol crystals.
