Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 3.758\% 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. O=[N+]([O-])c1ccc2c(c1)C(O)n1nc(-c3ccc(Cl)cc3Cl)nc1S2
b. CC(=O)Nc1ccc(OC(=O)c2ccc(Cl)cc2)cc1
c. O=c1c2c(-c3ccc(Cl)cc3)csc2ncn1/N=C/c1cccc([N+](=O)[O-])c1O
Answer: c. O=c1c2c(-c3ccc(Cl)cc3)csc2ncn1/N=C/c1cccc([N+](=O)[O-])c1O
