Final answer:
The word "verge" means border or edge, and the option that matches this meaning is "a) approach."
Step-by-step explanation:
The term "verge," defined as a border or edge, finds its counterpart in the option "a) approach." The word "approach" implies a deliberate movement towards a particular point, suggesting a progression that brings one closer to the border or edge of a defined space or concept. Just as one approaches a destination, the act of approaching inherently involves nearing the limits or boundaries of the target. This linguistic alignment emphasizes the nuanced connection between the action of approaching and the spatial or conceptual periphery, seamlessly capturing the essence of "verge" as a point of transition or boundary.
