Task: Answer the multiple choice question.
Question: Which compound exhibits a 17.505\% 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] CCCCN1C(=O)C(O)(CC(=O)c2ccccc2OC)c2ccccc21
[b] COCCNc1nc(C)cc(-c2cc(C(=O)NCc3ccccc3)on2)n1
[c] O=C(Cc1c(F)cccc1Cl)N1CCCC1
[d] Cc1ccc(S(=O)(=O)NCc2ccc(C(=O)N3CCc4ccccc4C3)cc2)cc1
[e] CCCC(=O)Nc1cccc(NC(=S)NC(=O)c2ccc([N+](=O)[O-])cc2)c1
Answer: c. O=C(Cc1c(F)cccc1Cl)N1CCCC1
