Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 4.123\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a) COc1ccc(OC)c(S(=O)(=O)Nc2ccc(-c3ccc4nncn4n3)cc2)c1
b) COC(=O)CN(c1ccccc1)S(=O)(=O)c1ccccc1
c) CCN(CC(O)COCc1ccc(Cl)cc1)C1CCCCC1.Cl
d) CC(=O)Nc1cc[n+](CC(=O)c2cccc([N+](=O)[O-])c2)cc1.[Cl-]
e) Cc1cccc(-n2c(O)c(C=Nc3ccc(O)cc3)c3ccccc3c2=O)n1
Answer: d. CC(=O)Nc1cc[n+](CC(=O)c2cccc([N+](=O)[O-])c2)cc1.[Cl-]
