An intentional act that causes another to reasonably fear or be apprehensive of immediate physical harm is a(n)

A) battery.
B) assault.
C) defamation.
D) intentional infliction of emotional distress.

Assault is the correct answer because it involves an act that intentionally causes another person to fear imminent physical harm. Battery, on the other hand, involves actual physical contact or harm. Defamation pertains to harm to a person's reputation through false statements, and intentional infliction of emotional distress involves extreme and outrageous conduct that causes severe emotional distress.
