Task: Answer the multiple-choice question.
Query: Which drug exhibits a -45.008% 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 other words.
Options:
[a] CC(C)CN1C(=O)NC2(CCCc3ccccc32)C1=O
[b] CCN1CCN(c2nc(N)c([N+](=O)[O-])c(Nc3cccc(C)c3)n2)CC1
Answer: b. CCN1CCN(c2nc(N)c([N+](=O)[O-])c(Nc3cccc(C)c3)n2)CC1
