Task: Answer the multiple-choice question.
Query: Which compound exhibits a 5.684\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
[a] COc1ccc(C(=O)Nc2c(N)nc(SCC(=O)Nc3ccc(C(C)=O)cc3)[nH]c2=O)cc1
[b] Cc1cc(C)c(CN2CCC(n3nccc3NC(=O)C3CCOC3)CC2)cc1C
[c] O=C(Cn1nnc(-c2cccs2)n1)NNC(=O)c1ccccc1Cl
Answer: c. O=C(Cn1nnc(-c2cccs2)n1)NNC(=O)c1ccccc1Cl
