Which of the following is an example of an autoclitic?

An autoclitic is a verbal behavior that modifies the meanings of other verbal operants, providing additional context or clarification about the speaker's intent or emotions.

In the example “I want that red one,” the phrase includes an autoclitic because it specifies the desire not just for a generic object but for a particular item characterized by its color. The inclusion of "that red one" enhances the original request for "want," indicating a specific preference. This added information clarifies the request, showcasing how the modification supports and elaborates on the meaning of the original verbal operant.

The other options do not contain elements that qualify as autoclitics to the same degree. They either express a straightforward request or pose a question without providing a layer of clarification about the speaker's emotional state or specific identification of something desired.
