Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 19.578\% 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 other words.
Options:
a: C=CCNc1ccc(N2C(=O)CCCC2=O)cc1[N+](=O)[O-]
b: O=C1CN2NC(=S)N(c3ccc(Cl)cc3)C2=CN1c1ccc(Cl)cc1
Answer: a. C=CCNc1ccc(N2C(=O)CCCC2=O)cc1[N+](=O)[O-]
