Trial and error would be the best strategy for James to use in this situation since he only has seven keys to try and he has no other information to go on. He can systematically try each key until he finds the one that works. Heuristics may not be effective in this situation as he has no prior experience with Danielle's keys, and information retrieval would be impossible without any information to retrieve. Hill-climbing is a problem-solving strategy that involves making small changes to a solution and seeing if those changes lead to an improvement, and it would not be applicable in this scenario.
