Task: Answer the multiple choice question.
Query: Which compound exhibits a -0.403\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a NS(=O)(=O)c1ccc(-c2ccc(C=NC3CCS(=O)(=O)C3)o2)cc1
b CN1CCN(c2ccc([N+](=O)[O-])c(N3CCCCC3)c2)CC1
Answer: a. NS(=O)(=O)c1ccc(-c2ccc(C=NC3CCS(=O)(=O)C3)o2)cc1
