Task: Answer the multiple choice question.
Question: Which drug exhibits a 17.102\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] CCCCN1C(=O)C(C)=C(C)C1OCCc1ccc(OC)c(OC)c1
[b] COC(=O)c1ccc(N(C(=O)CNC(=O)c2ccco2)C(C(=O)NC2CCCC2)c2ccco2)cc1
Answer: a. CCCCN1C(=O)C(C)=C(C)C1OCCc1ccc(OC)c(OC)c1
