which one of the following statements is true regarding global variables

I’d be happy to help!
Please provide the statements regarding global variables, and I’ll identify the true one(s) for you.

A global variable is accessible from any function or block of code in the program.
Global variables are defined outside of any function and are accessible from any other part of the program.

In programming, a global variable is a variable that is defined outside of any function or method and can be accessed by all functions and methods in the same program. Of the following statements, the true one regarding global variables is: “Global variables can simplify code by eliminating the need to pass variables between functions as arguments or return values.” However, it’s important to use global variables with caution, as they can lead to issues with variable naming conflicts and make code harder to test and debug.

Global variables are variables that are declared outside of any function or block in a program, making them accessible from any part of the code.
Here is a true statement regarding global variables:
Global variables can be accessed and modified by any function or block in a program, which can make the code difficult to understand, maintain, and debug. It is generally considered good programming practice to minimize the use of global variables and to use other types of variable scope (such as local or module-level variables) when possible. This helps to promote modularity, encapsulation, and other principles of structured programming.
