Task: Answer the multiple choice question.
Query: Which compound exhibits a -7.038\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
(a) CCOc1ccc(S(=O)(=O)N2CCN(C(=O)c3ccc(-n4cncn4)c([N+](=O)[O-])c3)CC2)cc1
(b) COc1ccc(CNC(=O)C/C(C)=N/NC(=O)COc2ccc(Br)cc2)cc1
Answer: b. COc1ccc(CNC(=O)C/C(C)=N/NC(=O)COc2ccc(Br)cc2)cc1
