Which items typically get a dome lid for serving?

The correct answer highlights the versatility and presentation needs of custards, shakes, and malts, which all benefit from the use of a dome lid for serving. Dome lids are designed to provide extra height and accommodate whipped toppings or other garnishes that accompany these creamy desserts. The curved shape of the dome allows for a stylish presentation while also preventing spills, making it ideal for beverages or desserts that can be layered or topped.

Ice cream sundaes can also be served with dome lids, but they are more commonly encountered in traditional bowls without them. Milkshakes may sometimes be served with lids, however, the dome design is not as essential since they typically don't have the same topping needs as custards and malts. Frozen yogurt cups can be served with dome lids as well, but they might not necessitate them in the same way as the rich, creamy textures of custards and milkshakes, especially when it comes to serving styles.

Thus, the option representing custards, shakes, and malts stands out for its comprehensive use of dome lids, making it the most fitting choice in this context.
