Option 1 -> Starts with "influence" which cannot logically begin the sentence without context.
Option 2 -> Begins with "policymakers" making the sentence structure incomplete and illogical.
Option 3 -> Creates a coherent flow: subject (mental health disorders rising) → affected group (young people) → causes (academic pressure and social media influence) → solution needed (support from policymakers) → purpose (address crisis).
Option 4 -> Starting with "people" creates an incomplete subject without proper context.
Hence, Option 3: (D), (B), (A), (C) -> This arrangement forms the complete sentence: "Mental health disorders are rising among young people, due to academic pressure and social media influence, requiring increased support from policymakers, to address the growing mental health crisis." The sequence logically presents the problem, identifies the affected demographic, explains the causes, and proposes the necessary action. -> correct
