Task: Answer the multiple choice question.
Question: Which compound exhibits a 8.905\% 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, b, or c without using any other words.
Options:
a COc1cc([N+](=O)[O-])cc(/C=N/NC(=O)c2cc(-c3ccccc3)nc3ccccc23)c1O
b C#CCOc1cc(C2C3=C(COC3=O)Nc3cc4c(cc32)OCO4)ccc1OC
c C1CCCN(CCCCN2CCCCCC2)CC1.Cl
Answer: a. COc1cc([N+](=O)[O-])cc(/C=N/NC(=O)c2cc(-c3ccccc3)nc3ccccc23)c1O
