Task: Answer the multiple choice question.
Query: Which compound exhibits a 0.171\% 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(NCCc1ccc(Cl)cc1)C1CCN(S(=O)(=O)c2cccc3nonc23)CC1
b: Cc1c(N2C(=O)C(=O)/C(=C(/O)c3ccccc3)C2c2ccc(F)cc2)c(=O)n(-c2ccccc2)n1C
Answer: a. O=C(NCCc1ccc(Cl)cc1)C1CCN(S(=O)(=O)c2cccc3nonc23)CC1
