Task: Answer the multiple-choice question.
Question: Which drug exhibits a 8.636\% 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: CCOC(=O)c1c(C)n(C)c2ccc(OC(=O)c3ccco3)cc12
b: O=C(N[C@H](Cc1cc(=O)[nH]c2ccccc12)C(=O)O)c1ccc(Cl)cc1
Answer: a. CCOC(=O)c1c(C)n(C)c2ccc(OC(=O)c3ccco3)cc12
