Final answer:
The statement that code labels are visible only within the procedure they are created is generally true (A). Labels are limited in scope to improve organization and avoid conflicts, although there could be exceptions in some languages or with specific types of labels.
Step-by-step explanation:
By default, code labels are visible only within the procedure in which they are assigned (created). The answer to this is mostly A) True. In most programming languages, labels used for marking a point within the code are limited in scope to the function or procedure they are defined in. This scope limitation helps to keep the code organized and avoids label conflicts where different pieces of code have labels with the same name.
In a few cases, like with global labels in assembly language, labels might be visible outside of a local scope, but this is less common in high-level programming languages. It's also worth noting that the practice of using labels is generally uncommon in high-level modern programming languages which make use of structured programming constructs such as functions, methods, and classes.
