Which of the following methods is used to retrieve records in the recycle bin?

The method used to retrieve records in the recycle bin is indeed queryAll(). This method allows you to access all records, including those that have been soft-deleted and are present in the recycle bin. It provides a comprehensive result set that encompasses both active and deleted records, making it particularly useful when you want to recover or review deleted information.

The other methods listed do not serve this purpose. For instance, retrieve() is typically used to obtain specific fields of one or more records but does not access deleted records. The delete() method is actually employed to remove records permanently and thus would not be used for retrieval. Lastly, queryMore() is a method designed to fetch additional records when working with large datasets that exceed the limits of a single query response, but it also does not target the recycle bin specifically.
