Problem statement: Answer the multiple choice question.
Query: Which drug has a 18.652\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a COc1cccc(OCC(=O)N(C)Cc2nc(-c3cccc(C)c3)no2)c1
b CCN(C(=O)COC(=O)CSc1ccc([N+](=O)[O-])cc1)C1CCS(=O)(=O)C1
c CCOC(=O)C1=C(COC(=O)CSc2ccc(Br)cc2)NC(=O)NC1C
Answer: c. CCOC(=O)C1=C(COC(=O)CSc2ccc(Br)cc2)NC(=O)NC1C
