A Correct answer
Explanation

MIDP (Mobile Information Device Profile) for J2ME permits only one Display instance per MIDlet. The Display class uses a singleton pattern - calling getCurrent() or getDisplay() returns the single instance. This limitation exists because mobile devices had constrained resources and MIDP was designed for single-screen applications.
