When an object is no longer needed, the garbage collector returns the object's space to the free list, making that space available for other objects to use. This helps to optimize memory usage and performance. Option B is incorrect as it refers to disk storage, which may not be relevant for memory usage in all systems. Option C is incorrect as reducing the size of an array holding an object would not necessarily release the memory used by the object itself. Option D is incorrect as it refers to a data block being marked as deleted, which may not be the case for all objects.
