Task: Answer the multiple-choice question.
Question: Which compound exhibits a 20.351\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
[a] O=C(CN1c2ccccc2Sc2ccccc21)NNC(=O)Nc1ccc(Cl)cc1
[b] O=C(/C=C/c1ccco1)Nc1nc(-c2ccccc2)cs1
[c] O=[N+]([O-])c1ccc(-c2ccnc(-c3ccccc3)n2)cc1CS(=O)(=O)c1ccc(Cl)cc1
[d] Nc1c(C(=O)OCC2CCCO2)c2nc3ccccc3nc2n1Cc1cccs1
[e] CC(C)CN1CC(C(=O)O)CC1=O
Answer: e. CC(C)CN1CC(C(=O)O)CC1=O
