Which of the following is a universal affirmative form?

Explanation:
Universal affirmatives are statements that claim every member of the subject class also belongs to the predicate class. In other words, S is contained in P, or all S are P. For example, All humans are mortal expresses that every human has the property of being mortal. Among the options, the one that says All S are P fits this idea exactly: it makes an “all” claim about the relationship between S and P. The other forms describe different claims: some S is P asserts there exists at least one S that is P; no S is P asserts there are no shared members between S and P; some S is not P asserts there exists an S that is not in P.
