The correct answer is D. All of the above.
An agent’s authority is the power to act on behalf of another person, the principal. The extent of an agent’s authority depends on a number of factors, including the nature of the act or business for which the agent has been appointed, things which are incidental to the business or are usually done in carrying it out, and the usual customs and usages of the trade.
For example, if an agent is appointed to sell goods, they will have the authority to do things that are necessary to complete the sale, such as negotiating the price and terms of the sale. They may also have the authority to do things that are incidental to the sale, such as inspecting the goods and preparing the paperwork for the sale. However, they would not have the authority to do things that are outside the scope of their appointment, such as giving away the goods or making a contract on behalf of the principal that is not related to the sale of goods.
The usual customs and usages of the trade can also affect the extent of an agent’s authority. For example, in the real estate industry, it is customary for agents to have the authority to show properties to potential buyers and to accept offers on behalf of their principals. However, this is not always the case, and it is important to check the specific terms of the agency agreement to determine the extent of the agent’s authority.
In conclusion, the extent of an agent’s authority depends on a number of factors, including the nature of the act or business for which the agent has been appointed, things which are incidental to the business or are usually done in carrying it out, and the usual customs and usages of the trade. It is important to be aware of these factors when appointing an agent to act on your behalf.
