Task: Answer the multiple choice question.
Query: Which compound exhibits a 12.948\% human ether-à-go-go related gene (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)C1=C[C@@H](C(=O)OC)[C@@H]2C3=C(C(=O)C2(C)C)[C@H](c2ccccc2)[C@@H]2C(=O)N(C)C(=O)[C@@H]2[C@@H]3C1
b CC1(C)SC(=S)N(NC(=O)Nc2cccc3ccccc23)C1N(O)C(=O)Nc1ccccc1
c CC(=O)Nc1cccc(NC(C)=C(C#N)C#N)c1
Answer: c. CC(=O)Nc1cccc(NC(C)=C(C#N)C#N)c1
