सर्व विचारवंत साहित्यिक आहेत. काही साहित्यिक शिक्षक आहेत. या माहितीच्या आधारे अधिक ग्राह्य विधानाचा पर्याय निवडा.

The correct answer is Option C (Some writers are not teachers).

Key Points:
• This is a Syllogism problem relying on selecting the most 'probable' or 'acceptable' logical inference among the given choices.
• Statement 1: All thinkers (T) are writers (W). (T is a subset of W).
• Statement 2: Some writers (W) are teachers (Tr). (Intersection between W and Tr).
• All writers are thinkers (False, it's the reverse).
• All teachers are thinkers (False, no direct relation is given).
• All teachers are writers (False, only some are).
• 'Some writers are not teachers'. While in strict formal logic this isn't an absolute certainty (as 'some' can logically mean 'all' in pure mathematics), in conversational aptitude logic, if 'some writers are teachers', it strongly implies that the remaining 'some writers are not teachers'. Given the options, it is the only plausible and most 'probable' (अधिक ग्राह्य) inference.
• Key Takeaway: In conversational logic, 'Some A are B' can imply 'Some A are not B' as the most probable deduction when strict options fail.
