Task: Answer the multiple choice question.
Question: Which compound exhibits a 13.169\% 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 additional words.
Options:
a CC(C)=CC(=O)Nc1c(C)cc(C)cc1Cl
b CCOC(=O)c1[nH]c(COC(=O)CCCOc2ccccc2)c(C(=O)OCC)c1C
Answer: a. CC(C)=CC(=O)Nc1c(C)cc(C)cc1Cl
