Final answer:
The claim that nested loops or processes must be in the same function to be considered nested is false; nesting can occur within different functions or the main program body.
Step-by-step explanation:
The statement that two or more repetitive processes must be in the same user-defined function to be considered nested is false. Nesting refers to the placement of one loop inside another loop or a conditional statement inside another. This concept does not require the loops or conditional statements to be within the same function; they can be nested within each other even if they reside in different functions or in the main body of the program.
