Task: Answer the multiple-choice question.
Query: Which compound has a 5.200\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
(a) O=C1Nc2ccccc2Nc2ncccc21
(b) O=C(Nc1ccc(OCC(=O)N2CCC(Cc3ccccc3)CC2)cc1)c1ccco1
(c) O=C(/C=C/c1cccc([N+](=O)[O-])c1)Nc1ccc(Cl)cn1
(d) N#CCc1cc(-c2ccc(Cl)c(Cl)c2)n[nH]1
(e) Cc1nn(C(=O)c2ccco2)c(C)c1Sc1ccc([N+](=O)[O-])cc1
Answer: a. O=C1Nc2ccccc2Nc2ncccc21
