Task: Answer the multiple-choice question.
Question: Which drug has a 3.011\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: CCCCn1c(N)c(N(CCC(C)C)C(=O)c2cccc(N3C(=O)c4ccccc4C3=O)c2)c(=O)[nH]c1=O
b: O=C(Nc1ccc(OC(F)(F)F)cc1)c1ccc2nc[nH]c2c1
c: COc1cc(NC(=O)Cn2c([N+](=O)[O-])cnc2C)c(OC)cc1Cl
d: COc1ccc(NC(=O)c2c(NC(=O)CNCc3ccco3)sc3c2CCC3)cc1
e: CC1SC(c2ccccc2)N(CC(O)c2ccc([N+](=O)[O-])cc2)C1=O
Answer: b. O=C(Nc1ccc(OC(F)(F)F)cc1)c1ccc2nc[nH]c2c1
