Kylie has created some code designed to keep track of information about employees at a company. The code will be used by the company to create a database of personal information (like home address, phone humber, email address, etc.) and salary information. Since Kylie knows that the company will only need to do a few things with the program, she makes many procedures and variables private so as to "hide" the implementation. This doesn't affect the behavior of the code. What Kylie has done to her program is called...

A. data abstraction
B. procedural abstraction
C. parameterization

Option (A) is the correct answer to the given question.

Explanation:

The main objective of the data abstraction means to presenting the outside environment only with the important information and hide its factual details on the program or in the environment .In the real world example our mobile is working perfectly or not is the important details not the internal implementation of mobile.

As the Kylie is to track the information of the employee .The programming code is used to creating the database management system it mainly hides the implementation like variable so this behavior is known as Data Abstraction also it does not affect the internal behavior .

Others options are not  any features of programming language so these are incorrect options.
