Task: Answer the multiple choice question.
Question: Which drug exhibits a 13.184\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.

b: O=C(O)c1cccc(N2C(=O)c3cc([N+](=O)[O-])cc4cc([N+](=O)[O-])cc(c34)C2=O)c1
c: Cc1cc(C)c2nc(N(CCN(C)C)C(=O)c3ccc(S(=O)(=O)N(C)CC4CCCO4)cc3)sc2c1.Cl
d: Cn1c(=O)c2c(nc(N3CCN(c4ccccn4)CC3)n2Cc2ccccc2Cl)n(C)c1=O
Answer: b. O=C(O)c1cccc(N2C(=O)c3cc([N+](=O)[O-])cc4cc([N+](=O)[O-])cc(c34)C2=O)c1
