Answer Details

The most appropriate phrase to complete the sentence is "heads of state." This is because the sentence is referring to multiple people who hold the position of head of state. "Heads of state" is a plural noun phrase that correctly identifies these individuals. Option A ("heads of states") is not correct because the word "state" should not be pluralized in this context. Option C ("head of states") is also not correct for the same reason. Option D ("head of state") is singular and therefore does not fit the context of the sentence, which refers to a group of people. Therefore, the correct answer is B ("heads of state").
