Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 1.458\% 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) CCOC(=O)C1=C(c2ccccc2)NC(SCC(=O)NC2CCCCC2)=C(C#N)C1c1ccco1
(b) CCCCC(CCC(=O)NNC(=O)Cc1ccccc1)C(=O)O
Answer: b. CCCCC(CCC(=O)NNC(=O)Cc1ccccc1)C(=O)O
