Task: Answer the multiple choice question.
Question: Which drug exhibits a -21.521\% human ether-à-go-go related gene (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] N#Cc1ccc(C2=CC(=O)C[C@H](c3ccc4c(c3)OCO4)C2)cc1
[b] O=C(Cn1cnc([N+](=O)[O-])c1)c1ccc(Cl)cc1
Answer: a. N#Cc1ccc(C2=CC(=O)C[C@H](c3ccc4c(c3)OCO4)C2)cc1
