Final answer:
Hippuric acid crystals, which form through the metabolism of benzoic acid, appear in urine as long, thin hexagonal plates.The correct option is B.
Step-by-step explanation:
The crystal that appears in urine as a long, thin hexagonal plate and is linked to the ingestion of large amounts of benzoic acid is Hippuric acid.
This compound forms when the body metabolizes benzoic acid, which is a substance present in various fruits and vegetables, and in some dairy products like yogurt.
It becomes Hippuric acid after a biochemical reaction with glycine, and can lead to distinctive hexagonal crystals in the urine.The correct option is B.
