Problem statement: Answer the multiple choice question.
Question: Which compound has a 13.587\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] CNC(=O)c1[nH]cnc1C(=O)N[C@@H](CCCCNC(=O)OC(C)(C)C)C(=O)OC(C)(C)C
[b] CN(C)N1C(N)=C(C#N)C(c2ccccc2)C2=C1CC(C)(C)CC2=O
Answer: a. CNC(=O)c1[nH]cnc1C(=O)N[C@@H](CCCCNC(=O)OC(C)(C)C)C(=O)OC(C)(C)C
