Problem statement: Answer the multiple choice question.
Question: Which compound has a 2.277\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: COc1ccc(Cl)cc1N(CC(=O)N/N=C/c1ccc(OC(C)C)cc1)S(=O)(=O)c1ccc(C)c([N+](=O)[O-])c1
b: Cc1cccc(C)c1OCC(O)CNC(C)C.Cl
c: CCOc1cc(/C=C(/C(=O)N2CCOCC2)c2nc3ccccc3[nH]2)cc(Cl)c1OC
d: O=C(NCc1nnc(SCc2ccccc2)n1-c1ccccc1)C12CC3CC(CC(C3)C1)C2
Answer: c. CCOc1cc(/C=C(/C(=O)N2CCOCC2)c2nc3ccccc3[nH]2)cc(Cl)c1OC
