Task: Answer the MCQ question.
Question: Which drug exhibits a -0.138\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) COc1ccc(-n2cnnc2SC(C)C(=O)Nc2cccc([N+](=O)[O-])c2)cc1
(b) Cc1ccc(S(=O)(=O)N2CCCC2C(=O)Oc2ccccc2)cc1
(c) O=C(NCc1cccc(C(F)(F)F)c1)c1cccc(Cl)c1Cl
Answer: c. O=C(NCc1cccc(C(F)(F)F)c1)c1cccc(Cl)c1Cl
