‘Tally vault’ is a ________ A. Security mechanism B. Ledger a/c C. Cost category D. None of the above

Security mechanism
Ledger a/c
Cost category
None of the above

The correct answer is: A. Security mechanism

A tally vault is a security mechanism that allows users to store sensitive data in a secure location. The vault is encrypted and can only be accessed by authorized users. This makes it a safe place to store passwords, financial information, and other sensitive data.

A ledger account is a record of financial transactions. It is used to track income, expenses, and assets. A cost category is a group of expenses that are related to a specific activity or department.

Neither of these options is a security mechanism.
