Which term refers to the vertical extent from top to bottom or the measure of depth?

• A. Defecate
• B. Deteriorating
• C. Depth
• D. Constrict

Answer: (C)

Depth describes the vertical extent from top to bottom or how deep something is. It’s the measurement of how far down something goes, like the depth of water or the depth of a wound. The other options refer to unrelated ideas: defecate means to pass stool, deteriorating means getting worse, and constrict means to narrow or squeeze. So depth is the appropriate term for describing vertical distance.
