Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 17.267\% 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] COC(=O)CC(c1ccc(C#N)cc1)n1c(C)ccc1C
[b] CN1CCN(C2=C(Cl)C(=O)C(c3cnc(N4CCCCC4)s3)=C(Cl)C2=O)CC1
Answer: b. CN1CCN(C2=C(Cl)C(=O)C(c3cnc(N4CCCCC4)s3)=C(Cl)C2=O)CC1
