What does 'plod' suggest about someone's movement?

The term 'plod' suggests movement that is heavy and labored. When someone plods, they typically move in a slow, deliberate manner, often indicating fatigue or a lack of motivation. This descriptor evokes an image of someone trudging along, with a lack of energy or enthusiasm, which is why it aligns with the choice that describes heavy and labored movement. In literature and everyday use, 'plodding' often implies persistence despite difficulty, further emphasizing the effort involved in this kind of movement.

The other choices imply quicker, lighter, or more fluid types of movement, which do not fit the connotation of 'plod.' Instead, this word paints a clear picture of a person who is moving slowly and with great effort, capturing the essence of exhaustion or burden.
