Task: Answer the multiple choice question.
Query: Which compound has a 6.124\% 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 CCOc1ccc(CCNC(=O)c2cccc(C#N)c2)cc1OCC
b CCCOc1ccc(/C=C/c2[nH]c(=O)[nH]c(=O)c2[N+](=O)[O-])cc1OCC
c COc1ccc(C2Nc3ccccc3NC3=C2C(=O)CC(C)(C)C3)cc1
Answer: b. CCCOc1ccc(/C=C/c2[nH]c(=O)[nH]c(=O)c2[N+](=O)[O-])cc1OCC
