Consider the following reaction ${\mathrm{MnO}}_2+\mathrm{KOH}+{\mathrm{O}}_2\to \mathrm{A}+{\mathrm{H}}_2\mathrm{O}$. Product ' $\mathrm{A}$ ' in neutral or acidic medium disproportionate to give products ' $\mathrm{B}$ ' and ' $\mathrm{C}$ ' along with water. The sum of spin-only magnetic moment values of $\mathrm{B}$ and $\mathrm{C}$ is BM. (nearest integer) (Given atomic number of $\mathrm{Mn}$ is 25)
