D. 1

Answer

**Step-by-Step Solution:**

1. **Understanding the Urethra**: The urethra is a tube that carries urine from the bladder to the outside of the body. It plays a crucial role in the urinary system.

2. **Identifying Sphincters**: Sphincters are circular muscles that can constrict or relax to control the passage of fluids. In the context of the urethra, there are two main types of sphincters involved in urination.

3. **Types of Sphincters in the Urethra**:
- **Internal Urethral Sphincter**: This sphincter is located at the junction of the bladder and urethra. It is involuntary and helps to retain urine in the bladder.
- **External Urethral Sphincter**: This sphincter surrounds the urethra and is under voluntary control, allowing a person to consciously start or stop urination.

4. **Counting the Sphincters**: Since there are one internal and one external sphincter, we can conclude that there are a total of two sphincters present in the urethra.

5. **Final Answer**: Therefore, the answer to the question "How many sphincters are present in the urethra?" is **C. 2**.
