\( \mathrm{KBr} \) से \( \mathrm{HBr} \) प्राप्त करने के लिए सान्द्र \( \mathrm{H}_{2} \mathrm{SO}_{4} \) का प्रयोग नहीं किया जाता है क्योंकि यह :
(A) \( \mathrm{HBr} \) को आक्सीकृत कर देता है।
(B) \( \mathrm{HBr} \) को अपचयित कर देता है।
(C) \( \mathrm{HBr} \) में असमानुपातन क्रिया कर देता है।
(D) \( \mathrm{KBr} \) के साथ अत्यन्त धीमी गति से क्रिया करता है।
