Task: Answer the multiple choice question.
Question: Which drug exhibits a -0.570\% 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, or d without using any other words.
Options:
a O=C(CCC(=O)Nc1cc(C(F)(F)F)ccc1Cl)N/N=C\c1cc([N+](=O)[O-])ccc1O
b CC(=O)NC1CC2CCC(C1)N2Cc1ccc(C)cc1
c Cc1ccc(Cn2cnc3c(cnn3-c3ccc(F)cc3)c2=O)cc1
d O=C(Cn1nnc(-c2ccccc2)n1)OCc1ccccc1
Answer: b. CC(=O)NC1CC2CCC(C1)N2Cc1ccc(C)cc1
