Task: Answer the multiple choice question.
Question: Which compound exhibits a 4.468\% 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, b, or c without using any additional words.
Options:
a: COc1ccc(Nc2nnc(-c3ccc(O)cc3)c3ccccc23)cc1C(N)=O
b: COC(=O)CCC(NC(=O)OCc1ccccc1)C(=O)NC(CC(C)C)C(=O)OC
c: O=C(CCc1ccccc1)Nc1nc2nc(-c3ccccc3)cc(=O)n2[nH]1
Answer: b. COC(=O)CCC(NC(=O)OCc1ccccc1)C(=O)NC(CC(C)C)C(=O)OC
