Correct Option: A

AI Explanation

To answer this question, we need to understand the concept of redefining fields in programming.

In programming, fields are variables or data structures that hold values. They are defined with a specific data type and size.

When it comes to redefining an existing field, it depends on the programming language and the specific situation. However, in general, it is possible to redefine an existing field with a new field of a different size.

In this case, the question asks if we can redefine an existing X(100) field with a new field of X(200). The correct answer is A) Yes. This means that it is possible to redefine an existing field with a larger size, in this case, going from X(100) to X(200).

It is important to note that when redefining fields, you should consider the impact on the program and any potential issues that may arise from changing the size of the field.
