Synergism
occurs when the effect of one drug is enhanced by the presence of another drug.




I think the correct answer from the choices listed above is the third option. Synergism  occurs when the effect of one drug is enhanced by the presence of another drug. It occurs due to the interaction between two or more substances which produces a combined effect.
