Task: Answer the multiple choice question.
Query: Which compound exhibits a 8.417\% 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=C(Nc1cccc([N+](=O)[O-])c1)Nc1ccc2c(c1)OCCO2
b: Cc1ccc(Cc2c(C)nc3nc(SCC(=O)NCCCN4CCCCCC4)nn3c2C)cc1
Answer: a. O=C(Nc1cccc([N+](=O)[O-])c1)Nc1ccc2c(c1)OCCO2
