What are the seven sandwiches that are served fully covered?

The correct answer is C because it encompasses all the mentioned sandwiches that are served fully covered. Each sandwich listed in the other options contributes to the complete picture of what the establishment offers. Fully covered sandwiches generally refer to items that are prepared with a robust layer of bread, toppings, and sauces, creating a hearty meal.

In this case, the Reuben and Cheesesteak are classic sandwiches known for their generous fillings and layering that align with the definition. The Cordon Bleu, traditionally made with chicken, ham, and cheese, also fits the description as it is typically prepared in a way that fully encases its ingredients. Meanwhile, the additional sandwiches mentioned in the other choices, like the Veggie and Dagwood, also qualify as fully covered based on their preparation styles which offer a substantial form of sustenance when served.

The option that claims "All above mentioned sandwiches" effectively summarizes the selection, confirming that each individual sandwich listed in all choices is indeed served fully covered. This understanding is crucial for anyone looking to manage or work within a sandwich-serving establishment, ensuring consistency and awareness of the offerings provided to customers.
