Match the following.
| List I | List II |
| A. DBMS | I. ctrl + y |
| B. SQL | II. ctrl + z |
| C. REDO | III. Structured Query Language |
| D. UNDO | IV. Database Management System |
Choose the correct answer from the options given below :
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → A-IV, B-III, C-I, D-II
The abbreviations are expanded, and the two commands are matched to their usual keyboard shortcuts.
(A) DBMS — this matches (IV) Database Management System. Software such as Access for organising, processing and querying data.
(B) SQL — this matches (III) Structured Query Language. The language used to work with tables in a database.
(C) REDO — this matches (I) ctrl + y. It repeats an action that was just undone.
(D) UNDO — this matches (II) ctrl + z. It reverses the last action.
Note 1: The keyboard shortcuts ctrl + y and ctrl + z are not covered in any edition of the NCERT Accountancy textbook; the book’s Spreadsheet questions below give the Undo and Redo commands.
Note 2: This question is from the pre-rationalised NCERT book for items (A) DBMS and (B) SQL. The topic is not there in the latest NCERT book (2026-27), but it is still in the CUET 2026 syllabus, so do not skip it.
