Correct Answer: Creatinine

Solution : The correct option is Creatinine.

Creatinine is often present in the urine. It is a byproduct of the muscles' utilisation of energy. Creatinine is removed from the blood by the kidneys and excreted in the urine. Higher creatinine levels in the blood or urine might be a symptom of kidney problems. Blood proteins, red blood cells, and white blood cells, on the other hand, are not normally detected in urine under normal conditions.
