To answer this question, let's go through each option to understand why it is correct or incorrect:
Option A) It is used for individual data item in working-storage section.
This option is incorrect because the 88 level entry is not used for individual data items in the working-storage section. The 88 level entry is used for condition names, not data items.
Option B) It is used for items with the rename clause.
This option is incorrect because the 88 level entry is not used specifically for items with the rename clause. The 88 level entry is used for condition names.
Option C) It is used for a data item which redefines another data item.
This option is incorrect because the 88 level entry is not used for data items that redefine another data item. The 88 level entry is used for condition names.
Option D) It is used for a condition name which can have either a true or false.
This option is correct. The 88 level entry is used for condition names in COBOL. A condition name is a user-defined identifier that represents a condition that can have either a true or false value. The 88 level entry assigns a condition name to a specific value or values, allowing it to be used in conditionals to test for the true or false state.
The correct answer is Option D. This option is correct because the 88 level entry is used for a condition name that can have either a true or false value.
