Task: Answer the MCQ question.
Question: Which compound has a 3.175\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
[a] COC(=O)CSC1=C(C#N)C(c2ccc(C(C)C)cc2)CC(=O)N1
[b] CC(/C=C\c1cccnc1)=C/C(=O)O
[c] COc1cc(OC)cc(C(=O)N[C@H](C(=O)OCC(=O)Nc2cccnc2Cl)C(C)C)c1
Answer: b. CC(/C=C\c1cccnc1)=C/C(=O)O
