To answer this question, the user needs to know what the SEARCH ALL operation does and if it requires sorted tables.

The SEARCH ALL operation is used to find a specific record in a table that matches a given key value. It starts searching from the beginning of the table and stops when it finds the first matching record. If the table is not sorted, the search operation will have to check every record in the table, which can be slow and inefficient.

Therefore, the correct answer is:

The Answer is: A. True.

SEARCH ALL can only be applied to sorted tables for efficient search operations.
