Task: Answer the multiple-choice question.
Query: Which compound exhibits a 8.111\% 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 other words.
Options:
a) N#CC(C#N)=NNc1ccc([N+](=O)[O-])cc1
b) COc1cccc(C(=O)COC(=O)CCC(=O)c2ccccc2)c1
c) CS(=O)(=O)N1CCc2cc(-c3csc(NC(=O)Cc4ccccc4)n3)ccc21
Answer: a. N#CC(C#N)=NNc1ccc([N+](=O)[O-])cc1
