Answer
Correct Answer: Kaushik is not a student of my class
Explanation
Introduction / Context:This is the same syllogistic pattern earlier: “All S are I; Kaushik is not I.” Contraposition yields that Kaushik cannot be in S (the class). Avoid global generalizations beyond “my class.”
Given Data / Assumptions:
- S = students in my class; I = intelligent.
- All S → I; Kaushik is ¬I.
Concept / Approach:If membership in S guarantees I, then ¬I entails ¬S for that individual. Hence Kaushik ∉ S.
Step-by-Step Solution:
A contradicts the universal “All S are I.”B overgeneralizes beyond “my class.”C is the necessary conclusion by contraposition.D introduces a universal claim about “all others”; not provided.Final Answer:Kaushik is not a student of my class
