Task: Answer the multiple choice question.
Question: Which drug has a 11.214\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: COc1cc2c(cc1OC)C(C)N(S(=O)(=O)c1ccc(C)cc1)CC2
b: COc1ccc(OC)c(-c2csc(NC(=O)C3c4ccccc4Oc4ccccc43)n2)c1
c: O=C1CN(C(=O)CSc2nc3ccccc3n2CCc2ccccc2)c2ccccc2N1
d: Cc1cccc(CS(=O)(=O)c2ncc(Cl)c(C(=O)NCc3ccc4c(c3)OCO4)n2)c1
Answer: c. O=C1CN(C(=O)CSc2nc3ccccc3n2CCc2ccccc2)c2ccccc2N1
