$5BiO_3^- + 14H^+ + 2Mn^{2+} \to 5Bi^{3+} + 7H_2O + 2MnO_4^-$

(B) To check if the equation is balanced,we verify the number of atoms and the total charge on both sides for option $B$: Left side: $5 \times Bi$,$15 \times O$,$14 \times H$,$2 \times Mn$. Total charge: $(-5) + (+14) + (+4) = +13$. Right side: $5 \times Bi$,$7 \times O + 8 \times O = 15 \times O$,$14 \times H$,$2 \times Mn$. Total charge: $(+15) + (-2) = +13$. Since both atoms and charges are balanced,option $B$ is correct.
