What does "saunter" imply about a person's manner of walking?

The term "saunter" conveys a sense of walking in a relaxed, leisurely, and often slow manner. When someone is described as sauntering, it suggests that they are moving without any rush, enjoying their surroundings as they stroll. This leisurely pace can indicate a feeling of ease or a carefree attitude, as opposed to any sense of urgency or productivity that other walking styles might imply.

In contrast, the other options indicate different walking styles that do not align with the meaning of "saunter." A hurried manner denotes a sense of speed and urgency, walking with purpose signifies intent and direction, and vigorous energy implies a fast and dynamic movement, all of which stand in contrast to the relaxed connotation of sauntering. Thus, the choice that most accurately captures the essence of sauntering is the one indicating a lazy and slow approach to walking.
