Task: Answer the multiple choice question.
Question: Which drug has a -4.571% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) COc1ccc(-c2nc3n(c(=O)c2C#N)CCCS3)cc1
(b) CN1CCN(S(=O)(=O)c2cccc(C(=O)Nc3ccccc3N3CCOCC3)c2)CC1
(c) CCCCC(=O)Nc1cc(OC)c(NC(=S)NC)cc1OC
Answer: a. COc1ccc(-c2nc3n(c(=O)c2C#N)CCCS3)cc1
