Task: Answer the multiple choice question.
Question: Which compound exhibits a 8.371\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a COc1ccc(C2Nc3cccc4cccc(c34)N2)cc1
b CC(C)CN(C(=O)COC(=O)c1ccc2c(c1)OCO2)c1c(N)n(Cc2ccccc2)c(=O)[nH]c1=O
c O=c1[nH]c2ccccc2n1Cc1ccc(F)cc1
Answer: a. COc1ccc(C2Nc3cccc4cccc(c34)N2)cc1
