Option A is incorrect because we cannot assign an integer value directly to a Node pointer.
Option B is incorrect because we need to use the arrow operator (->) to access the item field of the Node pointer.
Option C is incorrect because we cannot use the dereference (*) operator on an integer value.
Option D is correct because it correctly accesses the item field of the Node pointer and assigns a value of 3 to it using the assignment operator (=).
