Which statement would strengthen Kayla's argument for using a straight-line routing plan?

To strengthen Kayla's argument for using a straight-line routing plan, the focus should be on the proximity of accounts and their organization. A statement that accounts are located in clusters some distance from one another highlights the effectiveness of a straight-line routing approach, as it suggests that grouping accounts together can optimize travel time and improve efficiency in visiting clients. Such a routing plan would allow for visiting clients in a systematic manner, minimizing the time spent on the road and maximizing client interaction.

While other statements hint at different needs or preferences, they do not directly address the benefits of a straight-line routing plan in terms of organization and travel efficiency. For example, stating that all accounts are in proximity may not warrant a straight-line approach if the sales routes can be more dynamic or tailored. Additionally, preferences of salespeople or requirements for frequent visits do not provide the structural rationale needed to validate the use of a straight-line routing system.

Therefore, mentioning clusters of accounts supports the argument by indicating that a more organized and straightforward routing plan would be advantageous for managing time and resources effectively.
