Balanced in basic solution

[From: ] [author: ] [Date: 11-09-18] [Hit: ]
i thought it was B just by balancing but i have no idea how to approach this question please help!!!-Basic (aqueous) solution essentially means you can add as many OH-s as you want.Although BrO works, it might not be what they are looking for.......
Okay this is under electrochemistry, and in my ap chem class we haven't even reviewed general chemistry and i have no clue or have ever seen this kind of question so please help me?
When this partial equation:
BrO^- + CrO2^- = Br^- + CrO4^2-
is balanced in basic solution with similest set of whole number coeffcients, the balanced equation will contain:
(a) 2OH^-
(b) 2BrO^-
(c) 3CrO2^-
(d) 4H2O
i thought it was B just by balancing but i have no idea how to approach this question please help!!!

BrO + CrO2 + 2OH -> Br + CrO4 + H2O

Although BrO works, it might not be what they are looking for.
