Task: Answer the multiple-choice question.
Question: Which compound exhibits a 2.737\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] O=C(CN1C(=O)NC2(CCc3ccccc32)C1=O)c1ccccc1
[b] CCC(C)C(=O)N1c2ccccc2C(=C2SC(C(=O)OC)=C(C(=O)OC)S2)C(=S)C1(C)C
Answer: b. CCC(C)C(=O)N1c2ccccc2C(=C2SC(C(=O)OC)=C(C(=O)OC)S2)C(=S)C1(C)C
