Task: Answer the multiple-choice question.
Query: Which compound exhibits a 2.860\% 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.) Cc1cccc(C(=O)N=c2c(C#N)cc3c(=O)n4cccc(C)c4nc3n2Cc2ccco2)c1
b.) CCCC(=O)Nc1ccccc1-c1nnc(SC)[nH]c1=O
c.) CC1(C)CC(=O)C(C=NCC2CCN(C(=S)Nc3cccc(Cl)c3)CC2)=C(O)C1
Answer: b. CCCC(=O)Nc1ccccc1-c1nnc(SC)[nH]c1=O
