Task: Answer the multiple-choice question.
Question: Which compound exhibits a -6.288\% 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 additional words.
Options:
a O=C(NCCCCC(NC(=O)c1ccc([N+](=O)[O-])cc1)C(=O)O)c1ccc([N+](=O)[O-])cc1
b Cc1ccc(OCCN2C(=O)OC(C)(C)C2(C)O)cc1
Answer: a. O=C(NCCCCC(NC(=O)c1ccc([N+](=O)[O-])cc1)C(=O)O)c1ccc([N+](=O)[O-])cc1
