To answer this question, you need to understand the use of level 66 in programming.
Level 66 is used for the Renames Clause in COBOL programming. The Renames Clause allows you to give an alternative name to a data item. It essentially creates another reference to the same data item, allowing you to access or modify the data using either name.
Option A) For Renames Clause - This option is correct because level 66 is specifically used for the Renames Clause in COBOL programming.
Option B) For Condition Names - This option is incorrect because level 88 is used for defining condition names in COBOL programming, not level 66.
Option C) Elementary level item. Cannot be subdivisions of other items (cannot be qualified), nor can they be subdivided themselves - This option is incorrect because level 66 is not used for defining elementary level items in COBOL programming.
Option D) All of the above - This option is incorrect because level 66 is not used for defining condition names or elementary level items. Therefore, it is not used for all of the above purposes.
The correct answer is A) For Renames Clause. This option is correct because level 66 is specifically used for the Renames Clause in COBOL programming.
