Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 20.641\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
[a] CCOC(=O)c1ccc(N=C2SC(C(=O)NCCc3ccccc3)CC(=O)N2C)cc1
[b] N#CC1=C(SCC(=O)NC23CC4CC(CC(C4)C2)C3)NC(=O)C(C#N)C12CCCCC2
Answer: a. CCOC(=O)c1ccc(N=C2SC(C(=O)NCCc3ccccc3)CC(=O)N2C)cc1
