The United Arab Emirates was formed in December 1971 as a federation of seven emirates: Abu Dhabi, Dubai, Sharjah, Ajman, Umm Al Quwain and Fujairah, with Ras Al Khaimah joining shortly after in early 1972 to complete the federation. Each of these seven emirates is ruled by its own hereditary sheikh or ruling family, and together they operate under a shared federal constitution, a Federal Supreme Council composed of the seven rulers, and a rotating or traditionally assigned presidency historically held by Abu Dhabi's ruler. Five is incorrect because it undercounts the federation, likely reflecting confusion with the six emirates that joined at the initial December 1971 signing, before Ras Al Khaimah's later accession, or simple misremembering of the total. Six is incorrect for a closely related reason: six was indeed the number of emirates that joined at the founding moment in December 1971, but this figure excludes Ras Al Khaimah, which joined the federation a few months later in 1972, making six an outdated or incomplete count rather than the current total. Nine is incorrect because it overcounts the federation; there is no historical or constitutional basis for nine constituent emirates, and this option functions purely as a plausible-sounding distractor. The most frequent exam confusion is candidates recalling the six founding emirates from December 1971 and forgetting Ras Al Khaimah's slightly later 1972 accession.
