Brief Explanations:

Thomas Hobbes's "Leviathan" concept in political philosophy refers to a powerful sovereign (often an absolute monarchy) that is established by the social contract to maintain order and protect people from the chaos of the state of nature. The first option ("popular will") is more associated with Rousseau's general will or democratic ideas, the second ("threat of foreign powers") is not related to Hobbes's Leviathan. The third option matches Hobbes's view of the sovereign's absolute power to ensure security.

Answer:

the power of absolute monarchy (the third option in the list)
