You are writing JavaScript code to provide drag and drop functionality for the circle image element. The event listener that responds to a pointerdown event for the circle calls a function that adds event listeners for the pointermove and pointerup events for the circle. The event listener for the pointerup event is not necessary and can be omitted should call a function that removes the event listeners for the pointermove and pointerup events а should call a function that calculates the difference between the pointer's current position and its position when the pointerdown event occurred should call a function that determines the position of the pointer when the pointerdown event is next fired
