A. Be stored only in the database.
B. Have both IN and OUT parameters.
C. Use the positional notation for parameters.
D. Return a BOOLEAN or VARCHAR2 data type.

And why?

What is your opinion and why?
What did you already search by yourself?

What does answer A mean? That you cannot have it stored in a file in your sourcecode versioning system?
What does C mean? A function by itself has no positional or named notation for parameters; it is the call to the function that has this.

That's what you get from dumps: BS answers.
