Task: Answer the multiple-choice question.
Query: Which compound has a 7.170% 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 additional words.
Options:
(a) O=c1[nH]c(/C=C/c2ccccc2)c([N+](=O)[O-])c(=O)[nH]1
(b) O=C(CC1NCCNC1=O)Nc1cccc([N+](=O)[O-])c1
(c) Cc1c(NC(=O)c2ccc(CC(C)C)o2)c(=O)n(-c2ccccc2)n1C
(d) CC(NC(=O)c1ccc(N(C)C)cc1)c1ccc(F)cc1
Answer: b. O=C(CC1NCCNC1=O)Nc1cccc([N+](=O)[O-])c1
