Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 16.216% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: CN1CC2([N+](=O)[O-])CC=C(Cl)C([N+](=O)[O-])(C1)C2
b: Cl.OC(c1cccc(Cl)c1)c1nccc2ccccc12
Answer: a. CN1CC2([N+](=O)[O-])CC=C(Cl)C([N+](=O)[O-])(C1)C2
