Task: Answer the multiple-choice question.
Query: Which compound has a 12.079\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: CNC(=O)c1ccc(Nc2nnc(C)c3ccccc23)cc1
b: O=C(COC(=O)CNC(=O)C1CCCCC1)Nc1ccccc1Cl
c: O=C(CSc1nc2ccccc2c(=O)n1-c1ccc(Cl)cc1)N/N=C/C=C/c1ccccc1[N+](=O)[O-]
Answer: a. CNC(=O)c1ccc(Nc2nnc(C)c3ccccc23)cc1
