Task: Answer the multiple-choice question.
Question: Which compound has a -21.067% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] CCOc1ccc(C(=O)N2CCN(Cc3ccccc3)CC2)cc1
[b] CC1(C)CC(=O)C(C=NCCN2CCN(C(=O)c3ccc(F)cc3)CC2)=C(O)C1
Answer: b. CC1(C)CC(=O)C(C=NCCN2CCN(C(=O)c3ccc(F)cc3)CC2)=C(O)C1
