Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 3.863\% 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) CCn1cc(CN2CCN(Cc3ccc(OC)c(C)c3C)C(CCO)C2)c(C)n1
b) C[C@H](NC(=O)c1ccco1)C(=O)Nc1ccc(C#N)cc1
c) Cc1cccc(NC(=O)CSc2nnc(CNC(=O)c3ccco3)n2C)c1
d) COc1ccc(-n2c(=O)c3ccccc3n(CC(=O)Nc3ccccc3OC)c2=O)cc1
e) COC(=O)c1ccc(COC(=O)CNC(=O)c2ccc(C)s2)cc1
Answer: b. C[C@H](NC(=O)c1ccco1)C(=O)Nc1ccc(C#N)cc1
