What distinguishes express authority from implied authority?

Express authority is clearly stated, typically through written or verbal communication, providing the agent with specific power to act on behalf of the principal in particular situations. This clarity delineates the agent's role and the limits of their authority, making it evident what actions they are permitted to take.

On the other hand, implied authority refers to the powers that are not explicitly granted but are inferred from the actions or circumstances surrounding the relationship between the agent and the principal. This type of authority arises from the necessity to carry out the express authority or from the customary practices in specific contexts.

Thus, the critical distinction is that express authority is explicitly communicated, while implied authority is derived from the nature of the agent's role and the needs of the principal, making the first option accurate and affirming the difference between these two forms of agency relationships.
