Task: Answer the multiple-choice question.
Question: Which compound exhibits a 18.000\% 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] COc1ccc(S(=O)(=O)NCC2CCCN(C(=O)c3ccccc3)C2)cc1
[b] O=C(Nc1ccsc1C(=O)NC1CC1)c1ccccc1
[c] COc1ccccc1NC(=O)COc1ccc(/C=N/NS(=O)(=O)c2ccc(C)cc2)cc1
Answer: c. COc1ccccc1NC(=O)COc1ccc(/C=N/NS(=O)(=O)c2ccc(C)cc2)cc1
