Task: Answer the multiple choice question.
Question: Which compound exhibits a -1.889\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] Nc1ccccc1N=Nc1ccccc1N
[b] CC1(C)CC(=O)c2sc(NS(=O)(=O)c3ccc([N+](=O)[O-])cc3)nc2C1
[c] CCCCn1c(N)c(N(CCC(C)C)C(=O)C2CC(=O)N(c3ccc4c(c3)OCCO4)C2)c(=O)[nH]c1=O
[d] CC1=C(C(=O)Nc2ccc(C)cc2C)C(c2cccc(Cl)c2)n2nc(C(=O)OC(C)C)nc2N1
Answer: d. CC1=C(C(=O)Nc2ccc(C)cc2C)C(c2cccc(Cl)c2)n2nc(C(=O)OC(C)C)nc2N1
