C Correct answer
Explanation

In database systems, the external level (or view level) provides a user-oriented view of data while hiding implementation details. When salary information is hidden from employees but accessible to directors, this is external level data hiding - different users see different views of the same data based on their access privileges. This abstraction layer separates how users see data from how it's physically stored.
