Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 14.155\% 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 additional words.
Options:
[a] CC(C)(C)C(=O)Nc1ccc(N=Nc2ccccc2)cc1
[b] CC(=O)Nc1cc2nc(C)n(Cc3ccc([N+](=O)[O-])cc3)c2nc1C
[c] COc1ccc(-c2cc(CCCC(=O)NCCc3ccccc3)no2)cc1
[d] CC(CN1CCCCC1)OC(=O)/C=C/c1ccccc1.Cl
Answer: b. CC(=O)Nc1cc2nc(C)n(Cc3ccc([N+](=O)[O-])cc3)c2nc1C
