Consider the following statements: Statement: all boys are honest  Surender is honest. Conclusion: I) surrender is boy II) all honest person are boys Of these conclusion

Start with the statement. All boys are honest means the set of boys sits entirely inside the set of honest people. Honest people form a larger circle. Surender being honest only places him somewhere in that larger circle; it does not tell us he is inside the smaller circle of boys.

• Conclusion I (Surender is a boy): Does not follow. Honesty is shared by boys and non-boys alike, so Surender could be a man, a woman, or anyone else in the honest group.
• Conclusion II (All honest persons are boys): Does not follow. This is the converse of the given statement. All boys are honest does not reverse to all honest are boys. Converting an A-type proposition this way is a classic invalid step.

Both conclusions fail, so the answer is D. The core concept is the logic of categorical propositions, which matters for Mains essays and for spotting faulty reasoning in policy arguments where conditional claims get reversed.

Trap: Aspirants accept conclusion II because the diagram looks symmetric, or they pick Surender as a boy by assuming honesty is a boy-only trait.
