D) NULL is the correct answer. The `while` loop consumes all the elements of the array, so the `current()` function will return NULL.

I think the output will be bool(false). The `each()` function returns false when it reaches the end of the array, so the `current()` function will return the last element of the array, which is 3.

I believe the output will be int(1). The `each()` function moves the internal array pointer to the next element, so `current()` will return the first element of the array, which is 1.
