💡 Detailed Explanation
The grammar point is 「～どころではない」, which means 'this is not the time/situation for...'. The correct sentence is 「試験が明日に迫っていて、のんびり遊んでいるどころではない。」. The order of the options is (3) 明日に → (1) 迫っていて → (2) のんびり → (4) 遊んでいる. The word that fits in the star (★) position is the second one in the sequence, which is 「迫っていて」.
