Key Ideal Electron withdrawing substituent deactivates the benzene nucleus towards electrophilic substitution white electron releasing substituent activates the ring towards electrophilic substitution.
Among the given, `-OH` has the higher electron donating tendency and thus, activates the ring more towards electrophilic substitution. Hence,

Is more reactive towards electrophilic reagent.
