What is a categorical statement?

A categorical statement is indeed best described as a statement that establishes a relationship between two categories. This type of statement asserts a connection or relationship that allows for an understanding of how the categories are related to one another. For instance, if one were to say, "All mammals are warm-blooded," this reflects a relationship between the category of mammals and the category of qualities related to being warm-blooded.

Categorical statements serve as foundational elements in logic and reasoning, often helping to create syllogisms and other forms of argumentative structures. They clarify how different groups or classes interact or are defined in relation to each other, which is crucial for making logical arguments or drawing conclusions in debate and advocacy contexts.

In contrast, the other options describe different types of statements or rhetorical strategies that do not define categorical statements accurately.
