Correct option is C
Introduction:
A syllogism is a logical argument that uses two premises to draw a conclusion. Each statement has three terms — Major (P), Minor (S), and Middle (M) — and the structure (arrangement of these terms) determines the figure of the syllogism.

Additional Information:
1. Translate statements into categorical form
Mood letters meaning:
A: Universal Affirmative (All M are P)
I: Particular Affirmative (Some S are M / Some S are P)
Darii (AII–1) is one of the valid moods of Aristotelian syllogisms.
Other valid moods in Figure 1 include:
AAA–1 (Barbara)
EAE–1 (Celarent)
AII–1 (Darii)
EIO–1 (Ferio)
"All actors are athletes"
Subject: actors (S)
Predicate: athletes (P)
Form: All S are P → A proposition (Universal Affirmative)
"Some actors are comedians"
Subject: actors (S)
Predicate: comedians (M)
Form: Some S are M → I proposition (Particular Affirmative)
Conclusion: "Some comedians are athletes"
Subject: comedians (M)
Predicate: athletes (P)
Form: Some M are P → I proposition
Premise 1: A (S, P)
Premise 2: I (S, M)
Conclusion: I (M, P)
Premise 1: S–P (Middle term = Subject in first premise)
Premise 2: S–M (Middle term = Subject in second premise)
1st Figure: M–P, S–M
2nd Figure: P–M, S–M
3rd Figure: M–P, M–S
4th Figure: P–M, M–S
Major term (P) = athletes (predicate of conclusion)
Minor term (M) = comedians (subject of conclusion)
Middle term (S) = actors
All S are P (middle = S, major = P)
Some S are M (middle = S, minor = M)
M = actors (middle term)
S = comedians (minor term)
P = athletes (major term)
AII; Ist Figure
AIA; IInd Figure
AII; IIIrd Figure
IAI; IVth Figure
So the argument form is:
2. Identify the Figure
The Figure depends on the position of the middle term (actors = S) in the premises.
That means the middle term is subject in both premises — unusual for valid syllogisms, but let's check the figure definition:
Figure is determined by the position of the middle term in the two premises:
But here we have:
Premise 1: S–P
Premise 2: S–M
We can rearrange premise order to fit standard form (major premise first: P related to M; minor premise: S related to M).
But in our case:
Conclusion: Some M are P.
So:
Major premise: should contain P.
Minor premise: should contain S (minor term) and middle term.
But wait — our given premises:
This is actually:
Middle term = S (actors)
Major term = P (athletes)
Minor term = M (comedians)
So:
Premise 1: Middle–Major (S–P)
Premise 2: Middle–Minor (S–M)
That’s Figure 3 (M–P, M–S) if we swap the order of premises? Let's align:
Standard form for Figure 3:
Premise 1: M–P
Premise 2: M–S
Conclusion: S–P
But our conclusion is M–P (Some comedians are athletes), so S = comedians? No — careful:
Let’s reassign:
Let
Then:
Premise 1: All M are P (All actors are athletes) → M–P
Premise 2: Some M are S (Some actors are comedians) → M–S
Conclusion: Some S are P (Some comedians are athletes) → S–P
That’s exactly Figure 3:
M–P
M–S
∴ S–P
3. Mood
Mood = types of propositions in order:
Premise 1: A (M–P)
Premise 2: I (M–S)
Conclusion: I (S–P)
So mood = AII
4. Check validity
Figure 3, Mood AII (Darapti) — in traditional logic (assuming existential import), this is valid.
In modern logic, without existential import, it’s invalid if "actors" is empty, but here we have "Some actors are comedians" which guarantees M is non-empty, so it’s valid.

We have AII; 3rd Figure
