Task: Answer the multiple-choice question.
Question: Which drug exhibits a 5.164\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a.) CC1CC(=O)N(c2ccc(N(C)Cc3ccccc3)c([N+](=O)[O-])c2)C1=O
b.) O=C(NNC(=O)c1ncc(Cl)c(Cl)c1Cl)c1ccc(F)cc1
Answer: a. CC1CC(=O)N(c2ccc(N(C)Cc3ccccc3)c([N+](=O)[O-])c2)C1=O
