Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -25.900% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] CC(=O)COc1ccc2c(-c3cccc([N+](=O)[O-])c3)cc(=O)oc2c1
[b] CCN(CC(=O)Nc1ccc(OC)cc1)C(=O)c1ccc2c(=O)n3c(nc2c1)CCC3
Answer: a. CC(=O)COc1ccc2c(-c3cccc([N+](=O)[O-])c3)cc(=O)oc2c1
