Task: Answer the multiple choice question.
Query: Which compound exhibits a 9.660\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] CCOCCCNC(=O)c1cc(Nc2ccc(OC)cc2OC)nc2ccccc12
[b] CC(=O)N/N=C(/c1ccccc1)C(O)c1ccccc1
Answer: b. CC(=O)N/N=C(/c1ccccc1)C(O)c1ccccc1
