Task: Answer the multiple choice question.
Question: Which compound exhibits a 14.799% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) O=C(c1cccc([N+](=O)[O-])c1)c1ccccn1
(b) CCN1C(=S)N[C@@H](c2ccccc2)C(C(=O)OC)=C1C
(c) CSc1nc(O)c(C(c2ccccc2Cl)c2c(O)nc(SC)[nH]c2=O)c(=O)[nH]1
Answer: b. CCN1C(=S)N[C@@H](c2ccccc2)C(C(=O)OC)=C1C
