Explanation:

The Last Touch Attribution Model in Salesforce Campaign Influence assigns credit to the last campaign that a prospect engaged with before the opportunity was created or closed. This model is ideal when the marketing team wants to understand which final campaign interactions had the greatest influence on conversion. For LenoxSoft, which is interested in the campaign that directly influenced a closed opportunity, the Last Touch Model provides the clearest insight. It helps the marketing team identify which final efforts (e.g., email sends, events, or content) were most effective in moving prospects across the finish line into a sales conversion.
