Task: Answer the multiple-choice question.
Question: Which compound exhibits a 9.322\% 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] CCC(OC(C)=O)c1cc2c(cc1[N+](=O)[O-])OCCO2
[b] COC(=O)c1c(NC(=O)COC(=O)CCS(=O)(=O)c2ccc(C)cc2)sc(C)c1C
Answer: a. CCC(OC(C)=O)c1cc2c(cc1[N+](=O)[O-])OCCO2
