3. Which vitamin deficiency is most likely to cause bleeding disorders?

Vitamin E is known for its antioxidant properties and role in immune function, not specifically related to bleeding disorders. Vitamin D plays a key role in calcium absorption and bone health, but it is not directly linked to blood clotting or bleeding disorders.

Eggs, beef, and poultry are not significant sources of carbohydrates compared to milk. In cheese making, lactose is removed as a by-product, reducing the carbohydrate content further.
