Task: Answer the multiple choice question.
Query: Which drug has a 12.289\% 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: CCOC(=O)C(CC(=O)O)=C(c1ccccc1)c1ccccc1
b: O=C(COC(=O)c1ccccn1)Nc1cccc(Cl)c1
Answer: b. O=C(COC(=O)c1ccccn1)Nc1cccc(Cl)c1
