Which term means to enlarge or expand?

• A. Dysfunction
• B. Empathy
• C. Dilate
• D. Equilibrium

Answer: (C)

The concept here is enlargement or widening. The term that fits is dilate, which means to make something larger or wider. In medical contexts, dilating an opening or vessel increases its diameter, such as dilating the pupil or a blood vessel to allow more light or flow. The other terms refer to different ideas: dysfunction is about impaired function, empathy is the ability to understand another’s feelings, and equilibrium is a state of balance. Because dilate specifically conveys the act of enlarging or expanding, it is the correct choice.
