Task: Answer the MCQ question.
Query: Which compound exhibits a 5.838\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
[a] Cc1ccccc1CS/C(Nc1ccccc1C)=C(\C#N)C(N)=O
[b] O=C(COC(=O)CCc1nc2ccccc2s1)NCc1ccco1
Answer: a. Cc1ccccc1CS/C(Nc1ccccc1C)=C(\C#N)C(N)=O
