Task: Answer the multiple-choice question.
Query: Which compound exhibits a 15.147\% 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(Nc1ccc(C2CC2(Cl)Cl)cc1)c1ccccc1Br
[b] COc1ccc(NC(=O)CN(C)S(=O)(=O)c2ccc3c(c2)c(=O)n(C)c(=O)n3C)cc1
[c] O=C(/C=C/c1ccccc1)N(Cc1cccs1)C1CCS(=O)(=O)C1
Answer: a. O=C(Nc1ccc(C2CC2(Cl)Cl)cc1)c1ccccc1Br
