Task: Answer the multiple-choice question.
Query: Which compound exhibits a -29.086% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
(a) O=Cc1ccc2noc(-c3ccc(F)cc3)c2c1
(b) O=C(NCc1ccccn1)c1ccc([N+](=O)[O-])cc1
(c) COc1ccc(NCC(=O)N/N=C/C(C)c2ccccc2)cc1
(d) O=C(OCc1ccc(Br)cc1)c1cccc(S(=O)(=O)N2CCCC2)c1
Answer: b. O=C(NCc1ccccn1)c1ccc([N+](=O)[O-])cc1
