Task: Answer the multiple choice question.
Question: Which compound exhibits a 9.389\% 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 additional words.
Options:
a. Brc1ccc(COc2cccc3cccnc23)cc1
b. COc1cccc(Nc2c([N+](=O)[O-])cncc2[N+](=O)[O-])c1
c. Cc1ccc(/C=C/C(=O)Nc2ccc([N+](=O)[O-])cc2)o1
Answer: b. COc1cccc(Nc2c([N+](=O)[O-])cncc2[N+](=O)[O-])c1
