Final answer:
AWK indeed allows users to declare and use their own variables, making it a flexible tool for text processing and data manipulation tasks in scripting.
Step-by-step explanation:
The statement that AWK allows the user to use variables of their own choice is A) True.
AWK is a powerful text-processing programming language that enables users to perform complex data manipulation tasks. When writing AWK scripts, users can create and use custom variables to store data, perform calculations, and control the flow of the script. These variables can have both local and global scope, providing flexibility in how data is managed and used within the script. Importantly, AWK also offers built-in variables that provide access to useful information such as the current record number (NR) or the number of fields in the record (NF).
