B Correct answer
Explanation

QUEUE adds items to a stack, and QUEUED() returns the count of items. After three QUEUE 'MINDWORKS' operations, the stack contains 3 items, so x=3. QUEUED() is a valid REXX built-in function. The string concatenation result and Null are incorrect - QUEUED returns a numeric count, not the stacked content.
