Task: Answer the multiple choice question.
Question: Which compound exhibits a 4.337\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a) O=C(c1cccc(NS(=O)(=O)c2cccc([N+](=O)[O-])c2)c1)N1CCOCC1
b) O=C(CN1C(=O)NC(Cc2ccccc2)C1=O)Nc1ccc(F)c(F)c1F
Answer: a. O=C(c1cccc(NS(=O)(=O)c2cccc([N+](=O)[O-])c2)c1)N1CCOCC1
