To determine the correct answer, let's analyze the options provided:

1. Ethics: This refers to a set of principles that guide behavior, often related to a specific profession or group. Ethics can encompass both right and wrong behavior but doesn't necessarily imply a personal belief system.

2. Morality: This is concerned with the beliefs about what is right and wrong behavior. Morality often varies from one individual to another or from one culture to another.

3. Professional Ethics: This is a subset of ethics that specifically pertains to the standards and principles governing a particular profession. It focuses on right and wrong behavior within that professional context.

4. None of these: This choice suggests that none of the aforementioned terms are correct.

Based on this analysis, the option that best describes a belief about what is considered right and wrong behavior is Morality. While ethics also deals with these concepts, it is broader and not necessarily an individual's belief system.

Thus, the correct answer is: Morality.
