Step-by-step solution

Adhere is always followed by to and is thus incorrect here. Similarly, abide is to be followed by ‘ by ’ which is not the case here. This can also be eliminated. Flout meaning to defy is the opposite of what is needed. Refer does not make sense in the statement. Only Comply which means to follow/abide by/adhere to is correct. Hence, option D is correct.
