To retrieve Tasks that are between 12 and 24 months old, we need to use a SOQL query that filters based on the CreatedDate. The query must exclude deleted records and include both active and archived tasks. Since Tasks can be archived after a certain period (typically 12 months), we must ensure the query includes these as well.
Option C is correct because it uses ALL ROWS in the SOQL query, which includes both active and archived (soft-deleted) records. The query also correctly uses a range for CreatedDate to ensure it selects Tasks created between 12 to 24 months ago.
Option A is incorrect because it does not include the ALL ROWS keyword, which is necessary to include archived Tasks in the results.
Option B is incorrect because it only retrieves Tasks created in the last 12 months, not between 12 to 24 months ago.
Option D is incorrect because it does not filter Tasks based on their creation date correctly to include only those that are between 12 and 24 months old.
