Task: Answer the multiple choice question.
Question: Which compound exhibits a 4.048\% 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] COc1ccc(N(C(C)C(=O)NCc2ccco2)S(C)(=O)=O)cc1
[b] Cn1c(SCc2nc3ccccc3s2)nnc1-c1ccc2c(c1)OCO2
[c] CC(Cl)(Cl)/C(=N/P(=S)(N1CCOCC1)N1CCOCC1)N1CCOCC1
[d] COc1cc2c(cc1OC)C1=C(C#N)CN(C3CCCCC3)CN1CC2
Answer: d. COc1cc2c(cc1OC)C1=C(C#N)CN(C3CCCCC3)CN1CC2
