Task: Answer the MCQ question.
Question: Which compound has a 1.138\% 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: COc1ccc(CCn2c(C)cc3c(c2=O)C(c2ccc4c(c2)OCO4)C(C#N)=C(N)O3)cc1OC
b: COc1ccc(C(=O)N2CCCC2(C#N)c2ccccc2)cc1[N+](=O)[O-]
Answer: a. COc1ccc(CCn2c(C)cc3c(c2=O)C(c2ccc4c(c2)OCO4)C(C#N)=C(N)O3)cc1OC
