Question

which of the following pertains to federalism?
the division of the military into different branches with specialities
the international relationship between allied nations
the division of power between the national and state governments

Explanation:

Federalism is defined as the system of government where power is divided between a central (national) government and regional (state) governments. The first option is about military branch division, not federalism. The second is about international relations of allied nations, not related to federalism's power - division within a single nation. The third option, "the division of power between the national and state governments", matches the definition of federalism.

Answer:

the division of power between the national and state governments
