Question

Quizplus · Accepted Answer

Papillae are small, rounded protuberances (bumps) on a part or organ of the body.
Dermal papillae are small bumps located on the dermis (middle part of the skin) that protrude into the epidermis (top part of the skin). At the surface of the skin in hands and feet, they appear as papillary ridges (known as fingerprints).
Lingual papillae are the small bumps on your tongue that give it its rough texture.
Renal papillae refer to the top bump of a renal pyramid that protrudes into the cavity of a calyx of the kidney. The collecting ducts discharge urine through the renal papilla of the renal pyramid.  
The major duodenal papilla is a rounded projection at the opening of the common bile duct and pancreatic duct that protrudes into the duodenum.

We know that "dermal" refers to the skin, so this must be the correct answer as the skin would be the part of the body that would leave behind fingerprints. We know "lingual" means tongue, "renal" means "kidney" and "duodenal" refers to the duodenum. None of these parts of the body could leave behind fingerprints.
