Problem statement: Answer the multiple choice question.
Query: Which drug has a 5.533\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a. COc1ccc(CNC(=O)CN2C(=O)NC(C)(c3ccc(Cl)cc3)C2=O)cc1
b. COc1ccc([N+](=O)[O-])cc1NC(=O)C(C)OC(=O)c1cccnc1Cl
c. Cc1ccc(NC(=O)/C(=C\c2ccccc2)NC(=O)/C=C/c2ccccc2)cc1
Answer: b. COc1ccc([N+](=O)[O-])cc1NC(=O)C(C)OC(=O)c1cccnc1Cl
