Which of the following is an example of an operant behavior and its consequences? A student:

A) enters a restaurant and sits down
B) enters a football stadium and looks at the scoreboard
C) studies and gets good grades
D) is late to work and is ignored by everyone

Option C describes an operant behavior (studying) and its consequences (good grades). Operant behaviors are those that are shaped by their consequences, meaning that the behavior is more likely to occur again in the future if it is followed by a desirable consequence. In this case, the behavior of studying is followed by the desirable consequence of getting good grades, which increases the likelihood of the student studying in the future. Options A, B, and D do not describe operant behaviors and their consequences.
