Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 14.365\% 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] COc1ccc(C)cc1N(CC(=O)Nc1ccc(S(=O)(=O)N2CCCC2)cc1)S(C)(=O)=O
[b] COc1ccc([C@H]2CC(=O)C=C(c3ccc4ccccc4c3)C2)cc1
[c] CCC(CC)C(=O)NCCNC(=O)C(CC)CC
Answer: c. CCC(CC)C(=O)NCCNC(=O)C(CC)CC
