    A)                                                                                                                                                                                            \[{{F}_{2}}>C{{l}_{2}}>B{{r}_{2}}>{{l}_{2}}\]: Oxidising power     

    B)                  HI > HBr > HCI > HF: Acidic property in water

    C)                 \[{{F}_{2}}>C{{l}_{2}}>B{{r}_{2}}>{{l}_{2}}\]: Electronegativity
