Explanation:

Definition of a Vegetarian:
A vegetarian is someone who does not consume meat or fish. They typically rely on plant-based foods for their nutrition.

Options Given:
a) Meat
b) Milk
c) Chicken
d) Egg

Identifying Vegetarian Food Item:
To determine which of the given options is a vegetarian food item, we need to understand if it is obtained from animals or not. Since vegetarians do not consume meat or fish, we can eliminate options a) Meat and c) Chicken as they both come from animals.

Milk:
Milk, the liquid produced by female mammals to nourish their young, is the remaining option b). Although it is obtained from animals (cows, goats, etc.), it is still considered a vegetarian food item. This is because milk is not the flesh or body part of the animal, but rather a secretion produced by the mammary glands. Milk does not involve the slaughter or harm of animals, making it suitable for vegetarians.

Vegetarianism and Milk Consumption:
Many vegetarians include milk and its products in their diet as it is a good source of calcium, protein, and other essential nutrients. However, it is important to note that some vegetarians, known as vegans, exclude all animal-derived products from their diet, including milk. They choose plant-based alternatives like soy milk, almond milk, or oat milk.

Conclusion:
In conclusion, the correct answer is option b) Milk. Although milk is obtained from animals, it is still considered a vegetarian food item as it is not the flesh or body part of the animal.
