Which term pertains to the abdomen or the area below the diaphragm?

• A. Abdominopelvic
• B. Abdominal
• C. Achromatism
• D. Acoustic

Answer: (B)

The key idea is how medical terms describe body regions. The root abdomin- means abdomen, and the suffix -al means pertaining to. So abdominal literally means pertaining to the abdomen, the area below the diaphragm. That directly matches the prompt’s focus on the abdomen.

A broader term, abdominopelvic, refers to both the abdomen and the pelvis, which is useful in other contexts but isn’t as precise for the single region described here. The remaining options don’t relate to anatomy of the body regions: achromatism is about color vision, and acoustic pertains to sound.
