CF3CO2H (trifluoroacetic acid) or CCl3CO2H (trichloroacetic acid)

Being more electronegative, fluorine reduces the negative charge on CF3CO2- to a greater extend than chlorine reduces the negative charge on Cl3CCO2-. Therefore CF3CO2- is a poorer bases than Cl3CO2-, which means CF3CO2H is a stronger acid than Cl3CO 2H.

Most probibly trifluracetic acid, because flurorine(fluor-) is a more reactive halogen than chlorine(cholro-).
