Task: Answer the multiple choice question.
Query: Which compound exhibits a 2.099\% 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] O=c1c2ccccc2ncn1-c1ccc(Cl)cc1[N+](=O)[O-]
[b] O=c1[nH]c(=O)n(Cc2ccccc2)c2nc(-c3ccco3)cc(C(F)(F)F)c12
[c] CCc1cccc(Nc2cc(C)nc3ncnn23)c1
Answer: c. CCc1cccc(Nc2cc(C)nc3ncnn23)c1
