Task: Answer the multiple choice question.
Question: Which drug exhibits a -4.574% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a.) O=c1c(Cc2ccccc2)c(O)cc(-c2cccs2)n1-c1ccccc1
b.) Cc1cc([N+](=O)[O-])nn1CC(=O)Nc1nccs1
Answer: b. Cc1cc([N+](=O)[O-])nn1CC(=O)Nc1nccs1
