The sales team receives a list of approximately 800 leads each morning from The marketing...

The correct answer is B. Data Import Wizard.

The list contains only approximately 800 leads, which is well within the Salesforce Data Import Wizard limit. Salesforce documentation states that Data Import Wizard can import leads and supports up to 50,000 records at a time. It is also the best standard tool here because the requirement includes preventing duplicate lead records during import.

Data Loader is better for large-volume or scheduled technical loads, but it does not provide the same simple duplicate-prevention import experience for this small daily lead list. Manual entry is inefficient, and DataLoader.io is not the standard Platform App Builder exam answer.
