Which feature is a component of a database application

I believe that these are multiple choices:

A. centralized data storage

B. increased data duplication

C. unlimited access to data

D. unique data for similar multiple applications

Database applications are most useful for providing centralized data that can be accessed securely by multiple users from different locations in a controlled manner. When we talk about centralized data storage, what we mean is that all information is in one place. This helps protect data and increases speed and efficiency.
