Which of the following is an example of a verbal operant?

A mand is indeed an example of a verbal operant. In behavior analysis, specifically in the context of B.F. Skinner's analysis of verbal behavior, a mand is a type of verbal behavior that is used to request or demand something. It is characterized by its functional purpose; when a person uses a mand, they are asking for something they need or want. This type of operant is driven by a specific motivation or need, making it distinct from other types of verbal behavior.

The other options represent different concepts that do not qualify as verbal operants. Task analysis refers to breaking down a task into smaller, more manageable parts to teach a skill, which is not a verbal behavior but rather a teaching method. Classroom management pertains to the strategies teachers use to maintain a productive classroom environment and does not involve the use of language in a verbal operant sense. Observation is a method of watching and recording behaviors to gather data and does not involve expressing a request or demand, which is fundamental to the definition of a mand.
