What does "capacious" imply about a container?

The term "capacious" is an adjective that specifically refers to the ability of a container to hold a large amount of something due to its spaciousness. When a container is described as capacious, it suggests that it has a significant capacity or volume, making it suitable for carrying or accommodating a considerable quantity. This makes choice C the most accurate answer, as it directly reflects the meaning of the word.

Other descriptions, such as small, dirty, or fragile, do not relate to the concept of capacity or volume represented by "capacious." Instead, they focus on entirely different attributes that do not convey the idea of spaciousness.
