Respuesta :
New Zealand's government is different from Australia's in a way that Nez Zealand does not have a written constitution. The correct answer is C.
Both New Zealand and Australia are ruled by the monarch of the United Kingdom, this similarity between these two countries means they are part of the same realm. Conversely, the main difference between New Zealand and Australia is that New Zealand does not have a written constitution (option C), instead the realm counts with multiple treaties, orders and court decisions but they are not part of the same document.
