Task: Answer the multiple-choice question.
Question: Which compound exhibits a 6.305\% 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] CCc1c(C(=O)N2CCN(c3ccccc3F)CC2)[nH]c(C)c1C(C)=O
[b] CCCC1(CCC)C(=O)NC(=NCc2ccccc2)NC1=O
Answer: a. CCc1c(C(=O)N2CCN(c3ccccc3F)CC2)[nH]c(C)c1C(C)=O
