Task: Answer the multiple choice question.
Query: Which drug exhibits a 6.317\% 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 other words.
Options:
a: Cl.N=c1n(CCCOc2ccccc2Cl)c2ccccc2n1CC(N)=O
b: CN(CC(=O)Nc1ccc(F)c(F)c1F)C(=O)Cn1cnc2c1c(=O)n(C)c(=O)n2C
c: C=CCn1c(SCC2CCCCO2)nc2sc(CC)cc2c1=O
d: COCCCNCC(O)COc1ccccc1F
Answer: b. CN(CC(=O)Nc1ccc(F)c(F)c1F)C(=O)Cn1cnc2c1c(=O)n(C)c(=O)n2C
