The correct answer describes the proper construction of a chained linked list with three nodes. In this choice, the first node is created and assigned to the head variable with a value of 1. The Next property of the head node is then set to refer to a new node containing the value 2, effectively linking the first and second nodes. Following that, the Next property of the second node is assigned to another new node containing the value 3. This creates a continuous chain, allowing traversal from the head node (1) to the second node (2) and finally to the third node (3).

In this structure, each node knows about the next node in the list, forming a coherent linked list. This setup is crucial for traversing the list and is a fundamental characteristic of linked lists in data structures.

Other options do not successfully create an entire linked list of three nodes in the same manner. For instance, one might initialize multiple nodes but fail to link them all correctly, which is essential for maintaining the chain. The answer chosen aligns with the necessary operations to create a fully linked structure, hence its correctness.
