Task: Answer the multiple-choice question.
Question: Which compound has a 4.519\% hERG inhibition at a concentration of 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(/C(C)=N/NC(=O)c2nc(C)cc(C)n2)cc1
[b] NC(=O)C(c1ccccc1)c1ncc(C(F)(F)F)cc1Cl
[c] CCOC(=O)N1CCN(S(=O)(=O)c2ccc(C(=O)Nc3ccc(F)cc3F)cc2)CC1
[d] CCOC(=O)N1CCN(S(=O)(=O)N2CCCC(C(=O)NCCc3ccc(C)cc3)C2)CC1
[e] O=C(Cc1ccccc1)Nc1ccc(C(=O)O)cc1
Answer: c. CCOC(=O)N1CCN(S(=O)(=O)c2ccc(C(=O)Nc3ccc(F)cc3F)cc2)CC1
