Task: Answer the multiple choice question.
Query: Which drug exhibits a 12.336\% 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 additional words.

a.) COc1ccc(/C=C(/NC(=O)c2ccco2)C(=O)N2CCOCC2)cc1
b.) O=C(CCCC(=O)c1ccccc1)NCCc1ccccc1
c.) CCOC(=O)C(C)Oc1cccc2c(=O)n(CC(=O)NCc3ccco3)ccc12
d.) Cc1ccc(NC(=S)Nc2ccc(Cl)c(Cl)c2)c(OC(F)F)c1
Answer: b. O=C(CCCC(=O)c1ccccc1)NCCc1ccccc1
