Which meal abbreviation refers to a dietary preference that excludes all meat but may include dairy?

The correct abbreviation for a dietary preference that excludes all meat but may include dairy is indeed the one represented by the letters AVML. AVML stands for "Asian Vegetarian Meal," which typically encompasses a vegetarian diet that refrains from meat but can include dairy products. This dietary choice is in alignment with many Asian dietary practices that focus on plant-based foods but do not eliminate dairy.

Understanding the context of why other options do not fit is important. For example, MOML stands for "Moslem Meal," which adheres to Halal guidelines and doesn't specifically focus on vegetarianism. SFML, or "Seafood Meal," clearly includes fish and seafood, which contradicts the idea of excluding all meat. Lastly, RVML denotes "Vegetarian Meal," which generally excludes all animal products, including dairy, making it incompatible with the criteria of including dairy products. Therefore, AVML is the only abbreviation that accurately represents a dietary preference that excludes all meat while potentially including dairy.
