Problem statement: Answer the MCQ question.
Question: Which drug exhibits a -6.291\% 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: O=C(Nc1cccc(F)c1)c1ccc(-c2ccccc2Cl)o1
b: CC1(C)CC(=O)C2=C(C1)N(CCN1CCOCC1)C1=C(C(=O)CC(C)(C)C1)C2c1cccc(F)c1
Answer: a. O=C(Nc1cccc(F)c1)c1ccc(-c2ccccc2Cl)o1
