The answer is A. The Imagery is used to create a picture in the mind of the reader. By using this phrase, it automatically transports the reader to a place during fall. They can immediately picture the color of the leaves, sound of the leaves crunching beneath their feet, the of the leaves brushing them as they pass, the reds and oranges, the smell of their surroundings, etc. This imagery is a device that helps put what the reader is reading into context and creates a stage that is more personal to the reader.
