Final answer:
The ethical trap in question is the fallacy of appeal to logic or the is-ought fallacy, which assumes that a solution is right simply because it makes logical sense.
Step-by-step explanation:
The ethical trap that involves the belief that if a solution makes sense, then it is right is known as the fallacy of appeal to logic or the is-ought fallacy. This trap assumes that what is logically or rationally consistent must also be morally right. However, logic and reason alone cannot determine what is morally right or wrong. Morality involves subjective values, emotions, and social norms that go beyond pure reasoning.
