How many ounces of soup are contained in a cup?

A standard serving of soup in a cup typically contains 8 ounces. This is a common measure used across many restaurants and dining establishments.

In the context of the question, the correct answer reflects that a cup of soup is generally understood to be a full cup measurement, which is equivalent to 8 ounces. Thus, this understanding is essential for accurately assessing portion sizes in a restaurant or menu context.

While some cups could theoretically hold less, such as 4 ounces, this is not the standard serving size for soup in the industry. A serving size of 10 ounces is also less common and might not be practical in a casual dining setting. Thus, the conventional measurement for a cup of soup being 8 ounces is the basis for why that answer is correct.
