All of the options mentioned are used in Database Management Systems (DBMS) to ensure data accuracy and consistency.

a. Primary Keying: A primary key is a unique identifier for a record in a table. It helps maintain data integrity by ensuring that no two records have the same primary key value.

b. Check Constraints: These are rules that are applied to data in a table to ensure certain conditions are met. This helps maintain data integrity by preventing invalid data from being entered into the table.

c. Referential Integrity: This is a concept in which multiple database tables share a relationship based on the data stored in the tables, and that relationship must remain consistent. This is usually enforced with the use of foreign keys.

d. Field-level validations: These are checks at the field level to ensure the data entered into a field meets certain conditions, such as data type, data length, etc.

So, all of the above (Primary keying, Check constraints, Referential integrity, Field-level validations) are used in DBMS to make sure that data are accurate and consistent.
