Task: Answer the multiple-choice question.
Question: Which drug exhibits a 12.879\% 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: CCOC(=O)c1c(NS(C)(=O)=O)sc2c1CCC(C)C2
b: O=C(COC(=O)/C=C/c1ccc(Cl)cc1Cl)Nc1ccc2c(c1)OCCO2
c: O=C(CSc1nc2c(sc3ccccc32)c(=O)n1CCCN1CCOCC1)NC1CCCC1
Answer: b. O=C(COC(=O)/C=C/c1ccc(Cl)cc1Cl)Nc1ccc2c(c1)OCCO2
