Final answer:
The three standard ways to create an agency in California are typically through express agreement, implied authority, and ratification.
Step-by-step explanation:
In California, agencies can be created in three different ways, but it seems like there has been a mix-up in your question, as the options provided don't quite match standard methods of creating agency relationships. However, broadly speaking, the three main ways to create an agency are through express agreement, implied authority, and ratification.
An express agreement means both parties agree to the agency relationship, often in writing. Implied authority comes from the conduct of the parties, rather than a written or spoken agreement, suggesting that one party has the authority to act on behalf of the other. Ratification is when one party acts on behalf of another without prior authorization, and the principal later validates or confirms the agent's actions and decisions.
While it's important to clarify the context of your question, the standard methods to create agency are worth noting, even if they operate differently from forms of business organizations such as sole proprietorships, partnerships, and corporations, which have distinct features and are recognized as separate legal structures within which agency relationships might exist.
