Fundamental /Foundational Pharmacology question

The curve in the graph shown are idealized log dose-response curves obtained with increasing concentrations of an agonist during the measurement of a response, such as muscle contraction. Dose-response curves are obtained in the presence and absence of Drug X, which acts at the same receptor as the agonist. The most appropriate conclusion is the Drug X acts as which of the following 

A. competitive anatagonist

B. Inhibitor of the agonists inactivation

C. A noncompetitive antagonst

D. A partial agonist
