Task: Answer the multiple choice question.
Question: Which compound has a 12.920\% 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: CC(=O)Nc1ccccc1-c1nc2ccc(C(=O)N3CCN(c4ccccc4)CC3)cc2[nH]c1=O
b: CCOC(=O)c1cn(-c2ccc(F)c(F)c2F)c2c(F)c(F)c(F)cc2c1=O
Answer: b. CCOC(=O)c1cn(-c2ccc(F)c(F)c2F)c2c(F)c(F)c(F)cc2c1=O
