Task: Answer the multiple choice question.
Question: Which compound exhibits a 20.233% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: Nc1nc(SCC(=O)NCc2ccc(F)cc2)[nH]c(=O)c1NC(=O)c1ccc(Cl)cc1
b: Cc1ccc(CNC(=O)/C=C/c2c(Cl)cccc2Cl)cc1
c: COc1cccc(CNCc2ccc(OC)c3ccccc23)c1OC.O=C(O)C(=O)O
d: COc1ccc(Br)cc1C1Nc2cccc3cccc(c23)N1
e: Cc1nn(-c2ccccc2)c2nc(N)c(C#N)c(-c3ccc(C(C)(C)C)cc3)c12
Answer: d. COc1ccc(Br)cc1C1Nc2cccc3cccc(c23)N1
