Problem statement: Answer the multiple-choice question.
Query: Which drug has a 3.690\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: CN(C(=O)Oc1ccc(C(=O)c2ccc(Cl)cc2)cc1)c1ccccc1
b: O=C(Nc1ccc([N+](=O)[O-])cc1)N1CCc2ccccc2C1
c: COc1ccc(OC)c(NC(=O)C2C3CCC(C3=C(C)C)C2C(=O)O)c1
d: CCCc1ccc2oc(C(=O)N3CCNC(=O)C3CC(=O)OC)c(C)c2c1
e: Cc1ccc(OCC(=O)Nc2ccc(F)cc2)cc1
Answer: b. O=C(Nc1ccc([N+](=O)[O-])cc1)N1CCc2ccccc2C1
