Task: Answer the multiple-choice question.
Query: Which compound exhibits a 4.497\% 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 COc1ccc(C2(CNC(=O)c3ccc(OC)c([N+](=O)[O-])c3)CCOCC2)cc1OC
b COc1ccc(CN2CC34C=CC(O3)C(C(=O)O)C4C2=O)cc1
Answer: a. COc1ccc(C2(CNC(=O)c3ccc(OC)c([N+](=O)[O-])c3)CCOCC2)cc1OC
