Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 20.305\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] CC(C(=O)N1CCCC1)N(c1ccccc1)S(C)(=O)=O
[b] O=C(CN1CCN(S(=O)(=O)c2ccc(Br)cc2)CC1)N/N=C/c1ccccc1C(=O)O
[c] Cc1ccc(C2=Nc3ccccc3N(C(=O)c3ccccc3)C(C)C2)cc1
Answer: a. CC(C(=O)N1CCCC1)N(c1ccccc1)S(C)(=O)=O
