Answer: The answer is C. Qualifiers of Uncertainty.
Explanation: The phrase "taken many missteps" implies that the speaker is uncertain about the effectiveness of the mission in Afghanistan and acknowledges that mistakes were made. The qualifier "many" further emphasizes this uncertainty and implies that there were numerous missteps taken over a long period of time. This framing illusion is an example of Qualifiers of Uncertainty, which is a common way that speakers use language to hedge their statements and express doubt or uncertainty about a particular topic.
