Task: Answer the MCQ question.
Query: Which drug has a 5.586\% 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(C(C#N)=C2C=CC(=NO)C=C2)cc1
b: CC(C)CNS(=O)(=O)c1ccc(S(=O)(=O)NC2CCOC(C)(C)C2)cc1
Answer: a. COc1ccc(C(C#N)=C2C=CC(=NO)C=C2)cc1
