Task: Answer the multiple choice question.
Question: Which drug exhibits a 20.800\% 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 other words.

b.) Cn1ncc(N=Cc2ccc([N+](=O)[O-])cc2)c1C(=O)Nc1ccccc1
c.) CCOC(=O)[C@@H]1[C@H]2COc3cc(OC)ccc3[C@H]2N2C(=O)N(c3ccc(F)cc3)C(=O)[C@@]12C
Answer: b. Cn1ncc(N=Cc2ccc([N+](=O)[O-])cc2)c1C(=O)Nc1ccccc1
