Task: Answer the multiple choice question.
Query: Which compound exhibits a 15.191\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: O=C1CN(C(=O)c2ccc(Cl)c(S(=O)(=O)N3CCc4ccccc43)c2)c2ccccc2N1
b: O=C(CN1CCOCC1)Nc1ccccc1Sc1ccc(Cl)cc1
Answer: b. O=C(CN1CCOCC1)Nc1ccccc1Sc1ccc(Cl)cc1
