Task: Answer the multiple-choice question.
Query: Which drug has a 12.725\% 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 O=C(CSc1nc2cc(Cl)ccc2s1)c1ccco1
b CCOC(=O)C1=C(COC(=O)COc2ccc(C#N)cc2)NC(=O)NC1C
Answer: b. CCOC(=O)C1=C(COC(=O)COc2ccc(C#N)cc2)NC(=O)NC1C
