Task: Answer the multiple choice question.
Query: Which compound has a 21.892\% 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) O=C(CC(=O)N/N=C\c1cccc(Cl)c1Cl)NCc1ccccc1
(b) Cc1ccc(CCNC(=O)Cc2ccc(NC3=NC4CS(=O)(=O)CC4S3)cc2)cc1
(c) NC(=O)CSC1=Nc2ccccc2C2=NC(CC(=O)NCc3cccs3)C(=O)N12
(d) COc1ccc(S(=O)(=O)Nc2ccc3c(c2)n(C)c(=O)n3C)cc1C
(e) C/C(=N\N1C(=O)c2ccccc2NC1c1ccco1)c1ccccc1O
Answer: e. C/C(=N\N1C(=O)c2ccccc2NC1c1ccco1)c1ccccc1O
