A particular affirmative proposition is expressed in the form βSome S are Pβ. It makes an existential claim that there exists at least one member of the subject class that belongs to the predicate class. In traditional logic it is labelled I-type, reflecting its particular quantity and affirmative quality. Therefore the statement described in the stem is a particular affirmative proposition.
Option A:
Option A, universal affirmative, asserts that all members of the subject class are included in the predicate class. This is far stronger than the minimal claim that at least one such member exists, so it does not match the description.
Option B:
Option B, universal negative, denies that any S are P and thus contradicts the assertion that some S are P. It clearly cannot be the correct classification.
Option C:
Option C is correct because particular affirmative precisely relates to propositions that affirm the predicate of at least one subject. This form plays an important role in discussions of existential import and the square of opposition.
Option D:
Option D, particular negative, states that some S are not P, which is negative in quality and therefore different from the affirmative assertion in the stem.
