Problem statement: Answer the multiple choice question.
Query: Which drug has a 0.496% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a. O=C1CSC(c2ccc([N+](=O)[O-])cc2)N1c1ccccc1F
b. Cc1cccc(NC(=O)Cn2nnc3ccccc32)c1
Answer: a. O=C1CSC(c2ccc([N+](=O)[O-])cc2)N1c1ccccc1F
