Task: Answer the multiple-choice question.
Query: Which drug exhibits a 0.676\% 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 additional words.
Options:
[a] COc1ccc(-c2cn3c(C)c(C(=O)N4CCN(c5ccc(F)cc5)CC4)sc3n2)cc1
[b] O=C(Nc1c(C(=O)N2CCCCC2)cnn1-c1ccccc1)c1ccco1
[c] Cc1cc(C(=O)N/N=C/c2cccc([N+](=O)[O-])c2)c(C)n1-c1ccccc1
Answer: c. Cc1cc(C(=O)N/N=C/c2cccc([N+](=O)[O-])c2)c(C)n1-c1ccccc1
