The answer to this question would be choice D. can change over time depending on domestic affairs
Explanation: The reason being is that a country's foreign policy basically helps dictate the relationship between a country and other countries. For example, lets pretend that a foreign policy is like your way of "interacting" with your friends. Moreover, lets just say that maybe one day one of your friends starts saying bad things about you. Now, you are probably going to feel hurt and thus you are going to change the way in which you "hang out" with your friend from now on- that is, of course, if you decide that you still want to hang out with them. This is basically the same case between countries. A country might sometimes just decide to stay away from its other country "friends" if they are probably in war (its like seeing two of your friends fighting and not wanting to get caught in the middle). For this reasons, a country's foreign policy changes depending on what is going on.
