The form of a categorical syllogism is a(n) :

A) determination of whether the conclusion is true or false
B) estimation of how listeners will feel about the conclusion
C) list of the forms of its premises and conclusion
D) indication of where the middle term appears in the premises
E) identification of its mood and figure

The form of a categorical syllogism refers to its mood and figure, which are identified by categorizing the propositions in the premises (such as A, E, I, or O) and determining which terms are the subject, predicate, and middle term. This allows us to analyze the logical structure of the argument and determine whether the conclusion necessarily follows from the premises. A, B, C, and D do not accurately describe the form of a categorical syllogism.
