Answer
Correct Answer: Surbhi is not a student of my class
Explanation
Introduction / Context:This is the same logical pattern as a prior item: combining a universal conditional with a specific negation to infer non-membership.
Given Data / Assumptions:
- Universal: Student(class) ⇒ Intelligent.
- Specific: Surbhi is not intelligent.
Concept / Approach:Use the contrapositive of the universal: Not Intelligent ⇒ Not Student(class). Apply it to Surbhi.
Step-by-Step Solution:
From A, derive the contrapositive. From B, apply it. Therefore, Surbhi is not a student of my class.Verification / Alternative check:Any model that keeps A true while B holds must place Surbhi outside the set of class students.
Why Other Options Are Wrong:
• (a) Advice, not a deduction.• (c) Contradicts A.• (d) Contradicts the contrapositive.• (e) Unstated.Common Pitfalls:Mistaking converse for contrapositive; adding real-world assumptions.
Final Answer:Surbhi is not a student of my class.
