Task: Answer the multiple-choice question.
Query: Which compound exhibits a 4.144% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a.) O=P(O)(O)/C=C(\Cl)c1ccccc1
b.) CCOC(=O)CN/C(C)=C(\C#N)C(N)=O
Answer: b. CCOC(=O)CN/C(C)=C(\C#N)C(N)=O
