Task: Answer the multiple choice question.
Question: Which compound has a 8.033\% 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] CCNC(=O)C/C(C)=N/NC(=O)C1CCCCC1
[b] Cc1ccc(Cl)c2c1NC(=O)C2(O)CC(=O)c1ccc(Br)cc1
Answer: a. CCNC(=O)C/C(C)=N/NC(=O)C1CCCCC1
