Final answer:
A basic configuration object is a program data structure created by a software engineer during some phase of the software development process.
Step-by-step explanation:
A basic configuration object is a program data structure created by a software engineer during some phase of the software development process. It is used to store and organize data within a software program. It determines the layout, types, and relationships of the data elements, which allows the program to access and manipulate the data effectively.
For example, in a word processing program, a basic configuration object may store information such as the font size, style, and colors used in the document. In a gaming program, it may store the player's score, level, and inventory.
Therefore, the correct answer to the question is 1) Program data structure.
