Task: Answer the multiple-choice question.
Question: Which compound has a -1.645\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: CC(O)CNc1nc2ccccc2n1CC(=O)NCC(F)(F)F
b: C=CCn1c(O)c(C(C)=Nc2ccc(C(=O)OCC)cc2)c(=O)[nH]c1=O
Answer: b. C=CCn1c(O)c(C(C)=Nc2ccc(C(=O)OCC)cc2)c(=O)[nH]c1=O
