Task: Answer the multiple choice question.
Question: Which drug exhibits a -0.627\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
(a) CSc1nnc(-c2cc(-c3ccc(C)cc3)nc3ccccc23)o1
(b) O=[N+]([O-])c1cccc(/C([O-])=C(/C(=S)Nc2ccccc2)[n+]2ccccc2)c1
(c) CCC(=O)N1CCN(c2c(Cl)cccc2[N+](=O)[O-])CC1
Answer: c. CCC(=O)N1CCN(c2c(Cl)cccc2[N+](=O)[O-])CC1
