Task: Answer the multiple choice question.
Query: Which compound exhibits a 14.682\% 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 Cc1ccc(NC(=O)N2CCCC2)cc1Cl
b O=C(NNc1c(Cl)cc(Cl)cc1Cl)c1cccc([N+](=O)[O-])c1
c CCOc1ccc2[nH]c(=O)c(CN(CCc3ccccc3)C(=O)N3CCOCC3)cc2c1
d N#C/C(=C/c1ccc([N+](=O)[O-])cc1)C(=O)Nc1ccccc1O
Answer: b. O=C(NNc1c(Cl)cc(Cl)cc1Cl)c1cccc([N+](=O)[O-])c1
