Task: Answer the multiple choice question.
Question: Which compound has a 9.726\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: COc1ccc(N(C(=O)CNC(=O)c2ccco2)C(C(=O)NC2CCCCC2)c2ccncc2)cc1
b: CC(C)CC(NS(=O)(=O)c1cc(C(=O)O)ccc1Cl)C(=O)O
Answer: b. CC(C)CC(NS(=O)(=O)c1cc(C(=O)O)ccc1Cl)C(=O)O
