Problem statement: Answer the multiple-choice question.
Query: Which drug has a 21.563\% 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 additional words.
Options:
(a) CCOc1ccc(N/N=C(/C#N)C(N)=O)cc1
(b) Cl.NCc1cc2c3c(c1)CCCN3CCC2
(c) O=[N+]([O-])c1ccc(O)c(/C=N/Nc2ncnc3c2cnn3-c2ccccc2)c1
(d) CCc1noc2c1/C(=N\O)CC(c1ccccc1)C2
(e) COC(=O)Nc1ccc(NC(C)=O)cc1
Answer: e. COC(=O)Nc1ccc(NC(C)=O)cc1
