Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 3.255\% 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 other words.
Options:
(a) CC1=NNC(=O)C1CCC(=O)N/N=C\c1ccccc1[N+](=O)[O-]
(b) O=C(/C=C/c1cccc([N+](=O)[O-])c1)N1CC[C@@]2(O)CCCC[C@H]2C1
Answer: a. CC1=NNC(=O)C1CCC(=O)N/N=C\c1ccccc1[N+](=O)[O-]
