Task: Answer the multiple choice question.
Query: Which drug has a -4.838% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a) COc1cccc(CNc2ccc([N+](=O)[O-])cc2C)c1
b) CCOC(=O)Cn1c2c(c(=N)c3ccccc31)CCC2.Cl
c) CCc1ccc(NC(=O)C(=O)NNC(=O)c2cccs2)cc1
Answer: a. COc1cccc(CNc2ccc([N+](=O)[O-])cc2C)c1
