Final answer:
Agents are never able to make themselves liable on contracts with third persons. Option a. is correct.
Step-by-step explanation:
The correct answer is a. Agents are never able to make themselves liable on contracts with third persons.
When acting as an agent, individuals represent the interests of their principal, who is the person or company they are working for. In contractual agreements with third parties, agents do not assume personal liability unless they intentionally make themselves liable by entering into the contract in their own name.
For example, if an agent signs a contract on behalf of a company, the principal (company) is usually responsible for fulfilling the terms of the contract. However, if the agent signs the contract using their own name and not as a representative of the company, they may be personally liable for the obligations under the contract.
