To answer this question, we need to understand the concept of an abstract definition of data and how it is presented.
Option A) FALSE - This option is incorrect because it states that the abstract definition of data is not presented in the form of a message or arguments. However, in many programming languages and systems, an abstract definition of data can indeed be presented as a message or arguments.
Option B) TRUE - This option is correct because it states that an abstract definition of data can be presented either as an entire document or as arguments to be mapped to a method invocation. This is true in many programming languages and systems where data can be encapsulated and passed around as messages or arguments.
Option C) Not always true - This option is incorrect because the statement in the question does not mention any exceptions or conditions where the abstract definition of data would not be presented as a message or arguments. Therefore, it is not accurate to say that it is not always true.
Option D) None of these - This option is incorrect because the correct answer is option B, as explained above.
The correct answer is B) TRUE. This option is correct because an abstract definition of data can indeed be presented either as an entire document or as arguments to be mapped to a method invocation.
