Explanation:

To insert a list of 25,000 records using deduplication for the Race_Track__c custom object, an app builder should use Data Loader. Data Loader is a tool that allows users to insert, update, delete, or export large amounts of data in Salesforce. Data Loader can also perform deduplication by matching records based on external ID fields or Salesforce record IDs. [Source]
