Task: Answer the multiple-choice question.
Question: Which drug exhibits a -1.478\% 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] COC(=O)C1=C(c2cccc(OC)c2OC)C[C@@H]2CC[C@H]1N2C
[b] Cc1ccc2c(c1)N/C(=C(/C(Sc1ccccc1)=C(Cl)Cl)[N+](=O)[O-])N2
Answer: a. COC(=O)C1=C(c2cccc(OC)c2OC)C[C@@H]2CC[C@H]1N2C
