Task: Answer the multiple choice question.
Question: Which compound exhibits a 12.417\% 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 other words.
Options:
[a] O=C(O)CC1S/C(=N/N=C/c2ccc(-c3ccc(Cl)c([N+](=O)[O-])c3)o2)NC1=O
[b] CCc1ccc(S(=O)(=O)Nc2cccc(C3OCCCO3)c2)cc1
Answer: b. CCc1ccc(S(=O)(=O)Nc2cccc(C3OCCCO3)c2)cc1
