Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 4.595\% 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.) C/C(=N\NC(=O)CNC(=O)c1ccc(Br)cc1)c1ccco1
b.) O=C(COc1ccc([N+](=O)[O-])cc1)N/N=C/c1ccccn1
Answer: b. O=C(COc1ccc([N+](=O)[O-])cc1)N/N=C/c1ccccn1
