Task: Answer the multiple-choice question.
Question: Which compound exhibits a 2.644\% 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. O=[N+]([O-])c1cccc(-c2csc(N/N=C/c3cccc(O)c3)n2)c1
b. O=C1CCCc2c1cc(C(=O)NCc1ccco1)c(=O)n2-c1ccccc1
Answer: a. O=[N+]([O-])c1cccc(-c2csc(N/N=C/c3cccc(O)c3)n2)c1
