Task: Answer the multiple choice question.
Query: Which compound exhibits a -32.873\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a.) O=C(Nc1cccnc1)c1cc(-c2ccc3c(c2)OCO3)on1
b.) CCOc1ccccc1C(=O)Nc1cc(C(=O)NCCc2ccccc2)ccc1Cl
c.) CC(C)(C)c1ccc(-n2ncc3c2CCCC3NC(=O)CCN2CCCO2)cc1
d.) O=C(COc1ccc([N+](=O)[O-])cc1)Nc1ccc(CN2CCOCC2)cc1
Answer: d. O=C(COc1ccc([N+](=O)[O-])cc1)Nc1ccc(CN2CCOCC2)cc1
