Final answer:
True, round brackets are not always necessary when invoking a BIF that requires no arguments; this depends on programming language rules and the type of function being called.
Step-by-step explanation:
The statement is True: Round brackets do not need to be used if you are invoking a Built-in Function (BIF) that does not require any arguments. In programming, functions that do not take any arguments are often seen with empty round brackets, but some languages and circumstances allow the omission of brackets for such function calls. For example, in Python, the print() function traditionally requires parentheses; however, in certain cases, like property accessors in other languages, no arguments or parentheses are required.
