Given below are two statements:
Statement I: In Square of opposition. the opposition between a universal propostition and its corresponding particular proposition is known as subalternation.
Statement II: The opposition between 'No S is P' and 'Some S is not P' is called subalternation.
In the light of the above statements, choose the correct answer from the options given below:

Correct option is A

Statement I:
· In the Square of Opposition, subalternation refers to the relationship where a universal proposition implies its corresponding particular proposition.
· Examples:
· "All S is P" (A) implies "Some S is P" (I).
· "No S is P" (E) implies "Some S is not P" (O).
· This matches the classical definition of subalternation. Therefore, Statement I is true.
Statement II:
· "No S is P" (E) is a universal negative, and "Some S is not P" (O) is a particular negative.
· The relationship between E and O in the traditional Square of Opposition is indeed subalternation, as the universal negative proposition ("No S is P") implies the particular negative proposition ("Some S is not P").
· This aligns with the definition of subalternation in Aristotelian logic. Hence, Statement II is also true.
Information Booster: 1. Subalternation exists between a universal and its corresponding particular proposition.
2. Universal truth implies particular truth (e.g., E → O and A → I).
3. Subalternation is unidirectional: a universal implies a particular, but not vice versa.
4. Other relationships in the Square of Opposition include:
· Contradiction (A ↔ O, E ↔ I).
· Contrariety (A ↔ E).
· Subcontrariety (I ↔ O).
