The complement of the event "all of the engines are free of defects" is "at least one of the engines is defective". This means that there is at least one engine that is not free of defects. Choice C represents this complement event. Choices A and D are incorrect because they describe the original event itself, not its complement. Choice B is also incorrect as it is the extreme opposite of the original event, and it is unlikely to happen in reality.
