A la carte is a type of menu in which each dish is ordered separately, and it is often served in a formal setting. When laying a table for a la carte service, a fish plate may be included, as fish is a popular dish on such menus. A fish plate is typically paired with a fish fork and a fish knife, which are specifically designed for eating fish. The fish fork has shorter tines and a wider head than a regular fork, while the fish knife has a serrated edge to make it easier to cut through the delicate flesh of fish. Therefore, the correct option is "fish knife and fish fork".
