Answer

**Step-by-Step Solution:**

1. **Understanding the Excretory System**: The excretory system in humans consists of several organs, including the kidneys, ureters, urinary bladder, and urethra. Each of these organs plays a crucial role in the process of urine formation and excretion.

2. **Function of the Kidneys**: The kidneys are bean-shaped organs that filter blood to remove waste products, such as urea and salts. They produce urine, which contains these waste products.

3. **Path of Urine**: Once urine is produced in the kidneys, it travels through the ureters. The ureters are tubes that carry urine from the kidneys to the urinary bladder.

4. **Storage of Urine**: The urinary bladder is a pear-shaped organ that stores urine until it is ready to be expelled from the body. It acts like a bag that collects urine.

5. **Excretion of Urine**: When the bladder is full, urine is expelled from the body through the urethra. The urethra is a muscular tube that connects the urinary bladder to the external environment, allowing for the elimination of urine.

6. **Identifying the Correct Answer**: Based on the information provided, the muscular tube through which stored urine is passed out of the body is the urethra.

**Final Answer**: The muscular tube through which stored urine is passed out of the body is called **C - Urethra**.
