Expert systems require significant resources in terms of time, money, and expertise to develop. They require input and knowledge from domain experts and the creation of "If...then" rules is typically a manual process, making them more complex than systems generated through data mining. Additionally, while expert systems have been shown to be useful in certain applications, they have not necessarily lived up to the expectation that they would replace human experts entirely. Therefore, option D is the correct statement. The other options; A, B, and C are not true statements about expert systems.
