Task: Answer the multiple choice question.
Query: Which drug exhibits a 3.717\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a O=C(Nc1cc([N+](=O)[O-])ccc1N1CCCCC1)c1ccco1
b COCCN1C(=O)c2ccc(C(=O)Nc3nccs3)cc2C1=O
Answer: a. O=C(Nc1cc([N+](=O)[O-])ccc1N1CCCCC1)c1ccco1
