Task: Answer the multiple choice question.
Query: Which compound has a 12.298\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: O=C(CC1CCCC1)NNC(=O)c1ccc(Br)cc1
b: COc1ccc(C2CC(c3ccccc3)Nc3nc(NC(=O)c4cccs4)nn32)cc1
c: CC(=O)NCCc1nc2cc(NS(=O)(=O)c3ccc(Cl)cc3)ccc2n1C
Answer: a. O=C(CC1CCCC1)NNC(=O)c1ccc(Br)cc1
