Task: Answer the multiple choice question.
Query: Which compound has a 15.775\% 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) C/C(N)=C(/C#N)C(=O)COC(=O)C1Cc2ccccc2CN1S(C)(=O)=O
b) NS(=O)(=O)c1ccc(CNC(=O)c2cc(-c3ccccc3)nc3ccccc23)cc1
Answer: a. C/C(N)=C(/C#N)C(=O)COC(=O)C1Cc2ccccc2CN1S(C)(=O)=O
