To answer this question, let's first understand what an X(100) field and an X(200) field represent.
In programming and data storage, the notation X(n) is commonly used to represent a field that can hold a character string of length n. For example, X(100) represents a field that can store a character string of up to 100 characters, and X(200) represents a field that can store a character string of up to 200 characters.
Now, coming back to the question, can we redefine an X(100) field with a field of X(200)?
The correct answer is A) True.
This is because when you redefine a field, you are essentially changing its definition or characteristics. In this case, you are changing the length limitation of the field from 100 characters to 200 characters. As long as the new field (X(200)) can accommodate the data that was originally stored in the old field (X(100)), you can successfully redefine the field without losing any data.
It's worth noting that redefining a field may require careful consideration, especially if the field is used in multiple parts of a program or if it affects other related data structures. It's important to ensure that the change is compatible with the overall system design.
