Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a -17.346\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: CN1CCN(c2ncnc3scc(-c4ccccc4Cl)c23)CC1
b: O=C(Cc1ccc([N+](=O)[O-])cc1)N/N=C/c1ccc([N+](=O)[O-])o1
c: O=C(Nc1ccc(Cl)cc1)N1CC2CC(C1)c1cccc(=O)n1C2
d: CCOc1ccc(CCNC(=O)c2c(C)noc2C)cc1OCC
e: Cc1cc(NC(=O)Cn2c(=O)c3c(ncn3CC(C)C)n(Cc3ccccc3)c2=O)no1
Answer: b. O=C(Cc1ccc([N+](=O)[O-])cc1)N/N=C/c1ccc([N+](=O)[O-])o1
