• A. Employment at will
• B. Respondeat superior
• C. Joint and several liability
• D. Ministerial duties

Answer: (A)

The main concept is employment at will—the principle that an employer may terminate an employee at any time for any reason or for no reason. This means termination can occur without a stated cause, as long as the reason isn’t illegal or constrained by a contract or statute. In practice, there are exceptions (such as illegal discrimination, retaliation, or public-policy constraints, and situations governed by an implied contract or a collective bargaining agreement), but absent those, at-will termination is allowed. The other terms relate to different ideas: one concerns an employer’s liability for employees’ actions while performing their duties; another concerns shared liability among multiple defendants; and the last describes routine duties that must be performed according to instructions, not termination rights.
