Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 1.977% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] CC1=CC(C)=Nc2ccc(C)cc2N1
[b] COc1ccc(S(=O)(=O)N2CCCOC2CNC(=O)C(=O)NCCCN2CCOCC2)cc1
[c] c1ccc(OCCOc2ncnc3ccccc23)cc1
[d] O=[N+]([O-])c1cc(-c2csc(NCCc3nc4cc(Cl)c(N5CCCCC5)cc4n3CCCO)n2)ccc1Cl
Answer: a. CC1=CC(C)=Nc2ccc(C)cc2N1
