Problem statement: Answer the multiple-choice question.
Question: Which drug has a -13.168\% 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) CCOC(=O)C1CC(c2ccc(Cl)cc2)=NNC1=O
(b) COc1cccc(NC(=O)Cn2cc(C(=O)C3CC3)c3ccccc32)c1
(c) O=S(=O)(c1cccs1)N1CCN(c2ncccn2)CC1
Answer: c. O=S(=O)(c1cccs1)N1CCN(c2ncccn2)CC1
