Task: Answer the MCQ question.
Query: Which drug exhibits a 12.845\% 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: COc1ccc([N+](=O)[O-])cc1N(CC(=O)NCc1ccco1)S(C)(=O)=O
b: CC(=O)c1ccccc1NC(=O)COc1ccc(N(C)S(=O)(=O)c2ccc(C)c(C)c2)cc1
Answer: a. COc1ccc([N+](=O)[O-])cc1N(CC(=O)NCc1ccco1)S(C)(=O)=O
