Global variables are ___________Question 4Answera.None of theseb.Both internal and externalc.Internald.External

Global variables are typically defined as variables that are accessible throughout an entire program, which can be declared outside of any function or block of code. This makes them different from local variables, which are restricted to the function or block in which they are defined.

In programming, global variables can be both internal and external depending on their scope. Internal global variables are defined within the same file or module and can be accessed by any function in that module. External global variables, on the other hand, can be defined in one file and accessed from other files through the use of import statements or declarations.
