Task: Answer the multiple choice question.
Query: Which drug exhibits a 5.608\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
[a] Cn1c(/C(C#N)=C2/CCCCCN2)nc2ccccc21
[b] CCOC(=O)C1CCCN(Cc2cc(=O)oc3cc(C)c(C(C)C)cc23)C1
Answer: a. Cn1c(/C(C#N)=C2/CCCCCN2)nc2ccccc21
