Problem statement: Answer the MCQ question.
Query: Which drug exhibits a -4.580\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a.) COc1cccc(NC(=O)c2cccc(Cl)c2)c1
b.) CCC(C)N(NC(C)=O)c1nc(Cl)nc(NC(C)C)n1
c.) CC(=O)OCc1c(COC(C)=O)[n+](=O)c2ccccc2n1[O-]
Answer: c. CC(=O)OCc1c(COC(C)=O)[n+](=O)c2ccccc2n1[O-]
