First, we need to identify the oxidation numbers of each element in the equation. We can assign the oxidation number of F as -1, and Br as +5 in BrO and +1 in the other compounds. Then, we have:

BrO3- + Br- + F- --> Br- + F- + BrO2- + SO42-

In basic solution, we need to balance the equation by adding OH- ions to both sides of the equation. The balanced equation is:

BrO3- + 6Br- + 6F- + 6OH- --> 3Br2 + 6F- + BrO2- + SO42- + 3H2O

The sum of the smallest whole-number coefficients is 18, which is option C.
