A lactose-intolerant college student needs more vitamin D and calcium but avoids dairy. Which practical strategy best meets these needs while following dietary principles?

Avoid all milk alternatives because they are ineffective, rely exclusively on fast-food items that may occasionally contain calcium, and use tanning beds for vitamin D production.

Consume large quantities of unfortified rice milk and rely on small amounts of chocolate to meet calcium needs because taste preference is the primary consideration over nutrient density.

Consume fortified plant milks (e.g., fortified soy or almond milk) and fortified cereals for vitamin D and calcium, include fatty fish and leafy greens, and consider a vitamin D supplement if sunlight exposure is limited.

Take a daily high-dose vitamin A supplement instead since it provides the same benefits as calcium and vitamin D for bone health and is safer because it is fat-soluble.
