Which of the following actions may NOT result in an agent's imprisonment?

Failing to report a criminal prosecution in another jurisdiction may not directly lead to an agent's imprisonment, as it typically falls under regulatory violations rather than criminal offenses. While it is unethical and could result in disciplinary action, such as revocation of the agent's license or fines, it does not usually constitute a crime that would result in imprisonment.

In contrast, obtaining information about a consumer under false pretenses, engaging in insurance business after a conviction, and embezzling funds from the insurer are serious offenses that can lead to criminal charges and possibly imprisonment. These actions involve fraud, deceit, or criminal behavior that breaks the law, making them much more likely to result in incarceration. Thus, while all actions have consequences, failing to report a criminal prosecution is less likely to lead to imprisonment compared to the other options.
