Students with meal plans can purchase refreshments where?

The correct answer highlights that students with meal plans have the flexibility to purchase refreshments at POD stations and Starbucks, which are typically convenient locations on campus designed to cater to student needs. POD stations often feature a variety of snacks, beverages, and quick meals, while Starbucks provides a popular coffeehouse experience. This option reflects the offerings and convenience locations that align with a meal plan structure, allowing students to utilize their meal plan benefits in varied and accessible settings around campus for greater flexibility.

The other options don't offer the same breadth of purchasing locations that students with meal plans can actually access. Vending machines typically offer limited selections and may not fully accommodate meal plan usage. The library, while a place for study, often doesn’t feature a comprehensive meal plan offering. Similarly, residence halls might provide some options, but they are restricted compared to the variety and accessibility found at POD stations and Starbucks. In summary, option C provides the best context for where students can effectively use their meal plans to purchase refreshments.
