Problem statement: Answer the MCQ question.
Question: Which drug has a 0.564\% 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.) O=C(CSc1ncnc2ccccc12)c1ccc2c(c1)OCCO2
b.) CCCCC1C(C#N)=C(C)NC2=C1C(=O)CC(C)(C)C2
Answer: b. CCCCC1C(C#N)=C(C)NC2=C1C(=O)CC(C)(C)C2
