The right hypochondriac region is described as being on the right side of the abdomen covered by costal cartilages and lateral to the epigastric region.

• A. Right hypochondriac region
• B. Left hypochondriac region
• C. Right lumbar region
• D. Left lumbar region

Answer: (A)

Understanding the nine-region layout of the abdomen helps here. The hypochondriac regions are the upper lateral sections just beneath the costal margins. The term hypochondriac literally means below the cartilage of the ribs, so the right hypochondriac region is the upper-right area under the right ribs and, by design, lies to the side (lateral) of the epigastric region, which sits in the center of the upper abdomen. That combination exactly matches the description given, so this is the right hypochondriac region. The other options correspond to the left upper area or the middle right/left regions, which don’t fit the described position.
