नीचे दो कथन दिए गए हैं:
कथन I: \(O_2 N\)-\(C_6 H_4\)-\(CH^{\oplus}\)-\(C_6 H_4\)-\(OCH_3\) में, कार्बधनायन \(-OCH_3\) समूह के \(+R\) प्रभाव द्वारा स्थिर होता है।
कथन II: \(O_2 N\)-\(C_6 H_4\)-\(CH^{\ominus}\)-\(C_6 H_4\)-\(OCH_3\) में, कार्बऋणायन \(-NO_2\) समूह के \(-R\) प्रभाव द्वारा स्थिर होता है।
उपरोक्त कथनों के आधार पर, नीचे दिए गए विकल्पों में से सही उत्तर का चयन कीजिए:

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
