Task: Answer the multiple choice question.
Question: Which compound exhibits a 2.001\% 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(Nc1ccc(F)cc1F)NC1CCCc2ccccc21
(b) Oc1ccc(-c2nccc(-c3ccc(Cl)cc3Cl)n2)cc1
(c) CC(=O)c1ccc(N=Nc2ccc(N(C)C)cc2)cc1
(d) COc1cc(CN2CCNC(=O)C2CC(=O)NC2CCCC2)cc(OC)c1
(e) COc1ccc(CNC(=O)C2=C(C)C(=O)OC23CCC(C)CC3)cc1
Answer: a. O=C(Nc1ccc(F)cc1F)NC1CCCc2ccccc21
