The correct option is (a) Br2O > CI2O > F2O.
Explanation:

In OF2 repulsion between lone pairs is greater than that between bond pair since electrons are away from O and nearer to F. tn Cl2O, bonding electrons are nearer to O than to Cl, so the bond angle is greater than 109o28'. In Br2O, the bonding electrons are more closer to oxygen than in Cl2O, so the bond angle is largest (116o).
