Final answer:
Luminos Co.'s new product line Illuminia would be categorized as tableware, which includes items used for dining such as plates and bowls. It is distinct from cookware, glassware, and cutlery.
Step-by-step explanation:
Luminos Co., a renowned kitchen appliance manufacturer, is venturing into the manufacturing sector of crockery and dinnerware with its line called Illuminia. This new product line would most likely be categorized as tableware.
Tableware includes items such as plates, bowls, and serving dishes which are used for setting a table, serving food, and dining. It is different from cookware which is used for cooking purposes, glassware which is used to serve drinks and includes items made of glass, and cutlery which consists of utensils such as knives, forks, and spoons.
Lusterware is a related term that refers to a type of pottery known for its iridescent metallic glaze, often associated with historic ceramics. However, it doesn't directly apply to the product category for modern dinnerware, which primarily focuses on the functionality and use of the items rather than the specific decorative process used.
Therefore, the correct answer is 1) Tableware.
