Task: Answer the multiple choice question.
Question: Which compound exhibits a 9.775\% 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 COc1ccc(C2Nc3ccccc3C(=O)N2NS(=O)(=O)c2ccc(C)cc2)cc1OC
b O=C(NCCc1ccccc1)C1CCN(C2CCN(C(=O)CC3=CCCCC3)CC2)CC1
Answer: a. COc1ccc(C2Nc3ccccc3C(=O)N2NS(=O)(=O)c2ccc(C)cc2)cc1OC
