Final answer:
Universal agency is the most restrictive type of agency, while specific agency is the least restrictive.
Step-by-step explanation:
The most restrictive type of agency among the options provided is Universal agency. Universal agency is a type of agency where the agent has the authority to act on behalf of their principal in all matters, including making legal decisions. This type of agency is the broadest in terms of authority and gives the agent the most power to act on behalf of their principal.
On the other hand, specific agency is the least restrictive type of agency. In a specific agency, the agent is only authorized to act on behalf of their principal in specific and limited matters. This type of agency gives the agent a narrow scope of authority and restricts their decision-making capabilities.
Therefore, among the given options, universal agency is the most restrictive type of agency, while specific agency is the least restrictive.
