Task: Answer the multiple choice question.
Query: Which compound exhibits a -1.458\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] NC(=NC(=O)c1ccccc1)C1=C(O)CCC1=O
[b] Cn1c(=O)[nH]c(=O)c2c1nc(N1CCCCC1)n2CCSc1ncccn1
[c] CN1CCN(C(=S)SCC(=O)Nc2nc(-c3ccccc3)c(-c3ccccc3)o2)CC1
[d] O=C(Nc1cccnc1)c1ccc(NC(=O)c2ccco2)cc1
Answer: c. CN1CCN(C(=S)SCC(=O)Nc2nc(-c3ccccc3)c(-c3ccccc3)o2)CC1
