Task: Answer the multiple choice question.
Query: Which compound exhibits a 25.854\% 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: COc1ccc2[nH]c(=O)c(CN(CC3CCCO3)C(=S)Nc3cccc(C)c3)cc2c1
b: O=C(Nc1ccc(-c2nc3ccc(NC(=O)c4cccs4)cc3[nH]2)cc1)c1cccs1
c: CCC1(C)Cc2ccccc2-c2c1c(=O)n(Cc1ccccc1)c1nnnn21
Answer: a. COc1ccc2[nH]c(=O)c(CN(CC3CCCO3)C(=S)Nc3cccc(C)c3)cc2c1
