Electrophilic substitution reaction in phenol take place at:

A)  para position  

B)  meta position

C)  ortho position  

D)  o and p position

In phenol, oxygen atom containing two lone pair of electrons activates the benzene ring by increasing electron density at ortho and para position. Hence, the electrophile (electron deficient species) attacks on ortho and para position.
