Task: Answer the multiple choice question.
Question: Which drug has a -0.345\% 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. COc1ccccc1Oc1ccc(NC(=O)c2ccccc2)cc1
b. Cc1cc(NC(=O)C2CCN(C(=O)c3ccco3)CC2)ccc1Br
c. CCOc1ccc(N2C(=O)C(Cl)=C(Nc3ccccc3O)C2=O)cc1
Answer: c. CCOc1ccc(N2C(=O)C(Cl)=C(Nc3ccccc3O)C2=O)cc1
