Final answer:
The abdominopelvic region located between the right and left hypochondriac regions is the epigastric region. This region is used in medicine to describe the location of symptoms or findings in a detailed manner.
Step-by-step explanation:
The abdominopelvic region that is sandwiched between the right and left hypochondriac regions is the epigastric region (B). This means that the correct answer to the student's question is component 'B) epigastric'.
The abdominopelvic cavity is often used in medicine to describe locations of pains or masses and is divided either into nine regions for detailed descriptions or four quadrants for a simpler overview.
In the nine regions approach, the epigastric region is superior to the umbilical region, central and below the chest area, sharing borders with the right and left hypochondriac regions.
