Correct option is 1,2,3. because Br- changes to Br as it changes from -1 to 0. And in BrO3- Br changes from +5 to 0.Hope it clears. If u have doubts then please clearify. And if u like my answer then please approve answer

But what i have done is.. BrO3- is changing into Br2 hence BrO3- changes from -5 to 0 but if we balance we have to multiply 2 in BrO3- so it should be 10electrons.2BrO3- = Br2 hence 10 electrons...isn`t this the correct way.

In BrO3- Br is in +5 not in -5 and why you need to multiply by 2 as already 2 atom of Be are in LHS (one in Br- and one in BrO3- )and RHS.
