Task: Answer the multiple choice question.
Query: Which drug has a -3.772\% 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(-c2nc3ncccc3o2)ccc1Cl)c1ccc([N+](=O)[O-])o1
b) Cc1cc(C)cc(Oc2ccc(NC(=O)C3CC=CCC3C(=O)O)cc2)c1
Answer: a. O=C(Nc1cc(-c2nc3ncccc3o2)ccc1Cl)c1ccc([N+](=O)[O-])o1
