Task: Answer the MCQ question.
Question: Which compound exhibits a 3.371% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] COc1ccccc1CNC(=O)c1cc(-c2ccccc2C)n(CC2CC(c3cccc([N+](=O)[O-])c3)=NO2)n1
[b] CCOC(=O)C1=C(CSc2nc3c(cc2C#N)CN(C)CC3)OC(N)=C(C#N)C1c1ccncc1
[c] CC(C)CCNC(=O)C(c1ccc(O)cc1)N(Cc1cccs1)C(=O)C1COc2ccccc2O1
Answer: b. CCOC(=O)C1=C(CSc2nc3c(cc2C#N)CN(C)CC3)OC(N)=C(C#N)C1c1ccncc1
