**Core Concept**
Chyluria is a medical condition characterized by the presence of chyle in the urine, which is a milky fluid that contains triglycerides and other lipids. This condition occurs due to a communication between the lymphatic vessels and the urinary tract, allowing lymphatic fluid to enter the urinary system.

**Why the Correct Answer is Right**
Chyluria is associated with the passage of urine that contains chyle, which is a mixture of lymph, water, and lipids. The lymphatic fluid enters the urinary system through a fistula or communication between the lymphatic vessels and the urinary tract. This can occur due to various reasons such as filarial infection, tuberculosis, or trauma. The presence of chyle in the urine is a result of the breakdown of lymphatic vessels and the formation of a fistulous tract that allows lymphatic fluid to flow into the urinary system.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because chyluria is not associated with the passage of urine that contains blood. While some cases of chyluria may be associated with hematuria, the primary characteristic of chyluria is the presence of chyle in the urine, not blood.
**Option B:** This option is incorrect because chyluria is not associated with the passage of urine that contains pus. While some cases of chyluria may be associated with pyuria, the primary characteristic of chyluria is the presence of chyle in the urine, not pus.
**Option C:** This option is incorrect because chyluria is not associated with the passage of urine that contains glucose. While some cases of diabetes mellitus may be associated with glycosuria, the primary characteristic of chyluria is the presence of chyle in the urine, not glucose.

**Clinical Pearl / High-Yield Fact**
Chyluria is often associated with filarial infection, particularly in tropical regions. The presence of chyle in the urine can be a diagnostic clue for filarial infection, and prompt diagnosis and treatment are essential to prevent complications such as recurrent chyluria and lymphatic obstruction.

**Correct Answer: C.**
