What is defined as a power or demand established for the protection and benefit of a person?

The correct answer is the concept of a right. A right is defined as a power or demand that an individual possesses, which is recognized and protected by law or social norms. This can encompass various entitlements individuals have, such as the right to free speech, the right to privacy, or the right to make decisions about one’s own life and body. Rights are often established to ensure that individuals can exercise their freedoms and ensure their protection against infringement by others, including governmental bodies.

In contrast to rights, a duty involves an obligation to act in a certain way, often towards others, and does not inherently confer a protective demand for oneself. A privilege refers to a special advantage or benefit that is granted to an individual but is not universally available to all. Similarly, an obligation represents a responsibility or requirement to perform certain actions rather than a protective power for an individual. Thus, a right distinctly emphasizes the protective aspect that benefits the individual.
