Task: Answer the multiple choice question.
Query: Which compound has a 2.756\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
[a] O=C(COc1ccccc1Cc1ccccc1)Nc1cccc(S(=O)(=O)N2CCOCC2)c1
[b] COC(=O)c1ccc(-n2nnnc2SCC(=O)NCc2cccc(C(=O)O)c2)cc1
[c] O=C(Nc1cccc(C(=O)N2CCOCC2)c1)c1ccc([N+](=O)[O-])cc1
Answer: a. O=C(COc1ccccc1Cc1ccccc1)Nc1cccc(S(=O)(=O)N2CCOCC2)c1
