The best answer is B. lactose-free, vegan, or ovo-vegetarian.
- A lactose-free diet eliminates all milk products due to lactose intolerance.
- A vegan diet excludes all animal products, including milk.
- An ovo-vegetarian diet includes eggs but excludes dairy products, which aligns with June's restriction on milk products.
The other options include diets that may not necessarily exclude dairy products entirely (like diabetic and lacto-vegetarian).
