Task: Answer the multiple-choice question.
Query: Which compound exhibits a 15.850\% human ether-à-go-go related gene (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] COc1ccc(N(CC(=O)NCc2ccc3c(c2)OCO3)S(C)(=O)=O)cc1OC
[b] S=C(NCCc1cccc(Cl)c1)NCc1ccccc1
[c] O=C(/C=C\c1ccc2c(c1)OCO2)Nc1nnc(SCC(=O)OCc2ccccc2)s1
[d] Cc1noc(C(=O)Nc2cc(Cl)ccc2O)c1Cl
Answer: b. S=C(NCCc1cccc(Cl)c1)NCc1ccccc1
