Final answer:
Joanie hitting Lexie is an example of reactive aggression; it is an impulsive physical response to a perceived provocation during a game.
Step-by-step explanation:
An example of reactive aggression would be 'Joanie hits Lexie after Lexie bumps into her during a game of catch'. Reactive aggression is a response to a perceived threat or provocation. It is often impulsive and carried out in the heat of the moment. In the options provided, Joanie's action represents an aggressive behavior in reaction to being bumped, which she might have perceived as a provocation, even if it was accidental. The other examples either represent verbal aggression without physical action (Adrian calling Frank a sissy), consensual physical activity (Arthur wrestling Richie for fun), or unprovoked aggression (Marion punching Arnold for no apparent reason).
