Task: Answer the multiple-choice question.
Query: Which drug exhibits a 14.264\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a CN=C1SC(CC(=O)NCCc2ccc(OC)c(OC)c2)C(=O)N1C
b CC(=O)Nc1ccc(/C=C(\C#N)C(=O)NCc2ccccc2)cc1
c COc1ccccc1-c1nnc(N(C)C(=O)C2CCCO2)s1
d CCn1c(C)c(Br)c(=O)c(C(=O)OC)c1-c1ccc(Cl)cc1
Answer: b. CC(=O)Nc1ccc(/C=C(\C#N)C(=O)NCc2ccccc2)cc1
