The word "potency" refers to the power or effectiveness of something, in this case, the drug. The opposite of potency would be the lack of effectiveness or power.
Option C, "inefficacy," is the opposite in meaning as it indicates a lack of effectiveness or potency. Therefore, in the context of the sentence, acknowledging the potency of the drug suggests recognizing its effectiveness, while "inefficacy" implies the opposite – a lack of effectiveness.
