Task: Answer the multiple-choice question.
Question: Which drug exhibits a 1.513\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: Cc1nn(CC(=O)Nc2ccc(Cl)cn2)c(C)c1[N+](=O)[O-]
b: CC1=C(C#N)C(c2cccnc2)C2=C(CC(c3ccc(Cl)cc3)CC2=O)N1
Answer: a. Cc1nn(CC(=O)Nc2ccc(Cl)cn2)c(C)c1[N+](=O)[O-]
