Task: Answer the multiple choice question.
Query: Which compound exhibits a 14.378% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: CC(NC(=O)c1ccccc1NC(=O)c1ccco1)c1ccccc1
b: O=C(O)[C@H](Cc1ccccc1)Nc1ccc([N+](=O)[O-])cn1
c: OCc1c(OCc2cccc(F)c2)ccc2ccccc12
d: CCCOC(=O)CSc1nc(N)c(C#N)c(-c2ccco2)c1C#N
e: COc1cc(NC(=O)c2cc(-c3ccccc3Cl)on2)cc(OC)c1OC
Answer: b. O=C(O)[C@H](Cc1ccccc1)Nc1ccc([N+](=O)[O-])cn1
