Task: Answer the multiple choice question.
Question: Which compound has a 8.727% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a.) COc1ccc(-c2noc(CSc3nnc(CCc4ccccc4)n3-c3ccccc3)n2)cc1OC
b.) CC1=C(C(=O)OC(C)C)C(c2cccc([N+](=O)[O-])c2)n2c(cc(=O)[nH]c2=S)N1
Answer: b. CC1=C(C(=O)OC(C)C)C(c2cccc([N+](=O)[O-])c2)n2c(cc(=O)[nH]c2=S)N1
