Answer: (D)

Verified step by step guidance

1. Understand the concept of abdominopelvic quadrants: The abdominopelvic cavity is divided into four quadrants for anatomical reference. These quadrants are the Right Upper Quadrant (RUQ), Left Upper Quadrant (LUQ), Right Lower Quadrant (RLQ), and Left Lower Quadrant (LLQ).
2. Identify the location of the appendix: The appendix is a small tube-like structure attached to the cecum, which is part of the large intestine. It is located in the lower right side of the abdomen.
3. Relate the anatomical position of the appendix to the quadrants: Since the appendix is located in the lower right side of the abdomen, it falls within the Right Lower Quadrant (RLQ).
4. Review the anatomical landmarks: The RLQ contains several important structures including the cecum, appendix, and portions of the small intestine. This helps confirm the appendix's location within this quadrant.
5. Apply this knowledge to the problem: Based on the anatomical position and quadrant definitions, the appendix is housed in the Right Lower Quadrant (RLQ).
