Task: Answer the multiple choice question.
Query: Which compound has a 17.659\% 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.
Options:
a: Cn1c(N)c(C(=O)N/N=C/c2ccccc2)sc1=S
b: COc1ccc(C2=CC(=O)C[C@H](c3ccc4c(c3)OCO4)C2)cn1
c: O=C(C1CCN(S(=O)(=O)N2CCOCC2)CC1)N1CCC2(CC1)OCCO2
d: CC(=O)N1CCN(c2ccc(NCc3ccco3)cc2)CC1
Answer: a. Cn1c(N)c(C(=O)N/N=C/c2ccccc2)sc1=S
