Task: Answer the multiple choice question.
Query: Which compound exhibits a 21.215\% 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] O=C(CN1CCN(Cc2ccccc2F)C1=O)NCc1ccco1
[b] CCn1c(C)cc(/C=C2\SC(=O)N(CC(=O)Nc3ccc(C)c(C)c3)C2=O)c1C
[c] COc1ccccc1OCC(=O)NCc1cccs1
[d] CC(=O)Nc1ccc(S(=O)(=O)Nc2ccc(Nc3ccccc3)cc2)cc1
[e] COc1ccc(S(=O)(=O)N(CC(=O)NCc2ccco2)c2ccccc2OC)cc1
Answer: c. COc1ccccc1OCC(=O)NCc1cccs1
