\(C _6 H _3\left( NH _2\right)_2 COOH\) डाई ऐमीन बेंजोइक अम्ल के सभी संभव छह रुपों के विकार्बीक्सिलिकरण से \(A , B\) व \(C\) तीन प्रकार के उत्पाद प्राप्त होते है। तीन अम्ल उत्पाद ' \(A\) ' देते है, दो अम्ल उत्पाद ' \(B\) ' देते है तथा एक अमल उत्पाद ' \(C\) ' देता हैं तो उत्पाद ' \(C\) ' का गलनांक \(..........^{\circ}\,C\) है।

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.
