* Why Data Loader?
* Data Loader supports all standard and custom objects, including Opportunities.
* It is suitable for importing large data volumes like 500 records.
* Why Not Data Import Wizard?
* The Data Import Wizard does not support all objects, such as Opportunities.
* Why Not Other Options?
* A: Data Loader does not automatically relate Opportunities to Accounts unless provided external IDs.
* B: Data Loader is a desktop application, not browser-based.
* D: The Data Import Wizard can handle more than 500 records for supported objects, but it doesn't support Opportunities.
