On addition of small amount of \( \mathrm{KMnO}_{4} \) to concentrated \( \mathrm{H}_{2} \mathrm{SO}_{4} \), a green oily compound is obtained which is highly explosive in nature. Identify the compound from the following.
(a) \( \mathrm{Mn}_{2} \mathrm{O}_{7} \)
(b) \( \mathrm{MnO}_{2} \)
(c) \( \mathrm{MnSO}_{4} \)
(d) \( \mathrm{Mn}_{2} \mathrm{O}_{3} \)
