The assertion is partly true. While urea is a major contributor to the odor of urine, other substances such as creatinine and hormones may also contribute. The reason is also partly true, as urea can be converted into ammonia by bacteria present in the urinary tract, which can cause the characteristic odor of urine. However, some medical conditions such as diabetes and liver disease can also affect the odor of urine.

Option a is the correct answer.
