Task: Answer the MCQ question.
Question: Which compound has a -9.981\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: Cc1ccc(-c2nnc(NC(=O)C3=COCCO3)o2)c(C)c1
b: CCOC(=O)C1=C(C)OC(N)=C(C#N)C1c1cc(OC)c2c(c1)OCO2
Answer: b. CCOC(=O)C1=C(C)OC(N)=C(C#N)C1c1cc(OC)c2c(c1)OCO2
