The Correct Option is A, D
Solution and Explanation
Premises:
1. Soli likes either logic or biology.
2. If Soli likes logic, then he is not happy.
3. Neither Soli nor Rupinder likes biology. → So Soli cannot like biology.
Step 1: Apply premise (3)
Since Soli cannot like biology, the only option left is that Soli likes logic.
Step 2: Apply premise (2)
If Soli likes logic, then he is not happy. Therefore, Soli is not a happy person.
Step 3: Check options
(A) Soli is not a happy person → True.
(B) Rupinder is not a happy person → No information given.
(C) Rupinder is a happy person → No information given.
(D) Soli likes logic → True.
Thus, the correct conclusions are (A) and (D).
