Task: Answer the multiple choice question.
Question: Which compound has a 2.814\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: CCCCC1=CC2=C(c3ccco3)C(=O)C(C)(OC(=O)c3ccc(OC)cc3)C(=O)C2=CN1CC(C)C
b: COc1ccccc1NC(=O)COn1nnc2ccc(S(=O)(=O)N3CCOCC3)cc21
c: O=C(/C=C/c1ccccc1)NCC(=O)N/N=C/c1ccccc1[N+](=O)[O-]
d: CCCCCCCCCCCC(=O)N1CC(=O)NC(=O)C1
Answer: c. O=C(/C=C/c1ccccc1)NCC(=O)N/N=C/c1ccccc1[N+](=O)[O-]
