In subcontraries, the propositions are such that:
A) they could not both be false, but could both be true
B) they could not both be true, but could both be false
C) if the universal is true, then the particular must be true
D) if the universal is false, then the particular must be false
E) they cannot both be true, and they cannot both be false
Subcontraries
In the traditional square of opposition, a pair of propositions that, in virtue of their logical form, could both be true but could not both be false (I and O).
Universal
A characteristic or condition that applies to everything or everyone.
- Attain insight into the theories of subcontrary, contradiction, and contrariety in propositional logic.
- Determine the truth values of propositions based on the relationships within the square of opposition.

Final Answer :
A
Explanation :
Subcontraries are a pair of particular propositions in traditional logic (usually represented as "Some S are P" and "Some S are not P") where it is impossible for both to be false together because at least one of them must be true, but they can both be true if there is some overlap (i.e., some S are P and some S are not P).
