Explanation:

- Fiction Theory: Suggests that a corporation is an artificial person created by law. It's a legal construct without real personality.

- Will Theory: Focuses on individual human will and is associated with contractual obligations. It’s not typically linked to corporate personality theories.

- Realist Theory: Argues that corporations have a real, distinct existence in society. They are more than just legal constructs.

- Bracket Theory (Concession Theory): Proposes that a corporation’s legal personality is merely a “bracket” to facilitate the purpose defined by humans.

Option 2, Will Theory, is not related to corporate personality theories.
