Problem statement: Answer the multiple choice question.
Query: Which compound has a 17.961\% 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 other words.
Options:
a Cc1ccc(CN2CCN(/N=C\C(Br)=C\c3ccccc3)CC2)cc1
b CC(C)CC(NC(=O)c1ccco1)C(=O)Nc1ccc2c(c1)OCCO2
c CCCCCC(=O)N/N=C/c1ccccc1[N+](=O)[O-]
d COc1cc2c3c(c1)C1(C(=O)N3C(C)(C)C=C2C)C(C#N)=C(N)Oc2cc(O)ccc21
e C=CCc1ccccc1OCC(O)CNC(C)C.Cl
Answer: c. CCCCCC(=O)N/N=C/c1ccccc1[N+](=O)[O-]
