The strength of an acid can be determined by different methods among them pKa is one of the method .Lower the pKa volue of a compound more stronger acidic the compound will b and vice versa.
Among the 5 compouds the compound D will be having lower pKa value and stronger acid it will be,becoz in D compound there is CCl3 group which is having more electron drifting power towards itself and hydrogen will leave easily as proton .
so option D is correct option
