Task: Answer the multiple choice question.
Query: Which compound exhibits a 1.787\% 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(OC)c(NC(=O)c2ccc(S(=O)(=O)N3CCOCC3)cc2)c1
b O=C1CCC(CCC(=O)N2CCCC(C(=O)c3ccc4c5c(cccc35)CC4)C2)=NN1
c CCOC(=O)C(C)(C)Sc1nc2c(cnn2-c2ccc(Cl)cc2)c(=O)[nH]1
d Cc1cccc(C(=O)N2CC(=O)Nc3ccc(F)cc3C2c2ccc(F)cc2)c1
e COc1ccc(Nc2cc(C)nc(N3CCOCC3)n2)cc1
Answer: e. COc1ccc(Nc2cc(C)nc(N3CCOCC3)n2)cc1
