Option 1: (C), (A), (D), (B) -> "From a study of University enrollment figures, over the past decade, it is evident that women are increasingly opting for professional courses" - follows perfect logical flow: source → time frame → main statement → action.
Option 2: (A), (D), (C), (B) -> Places "from a study" awkwardly in the middle, disrupting grammatical structure.
Option 3: (B), (C), (D), (A) -> Starting with "increasingly opting" without a subject creates a grammatically nonsensical sentence.
Option 4: (D), (B), (C), (A) -> While somewhat comprehensible, placing the source and time frame at the end makes the sentence awkward and less effective.
Hence, Option 1: (C), (A), (D), (B) -> The sentence should begin with the source of evidence (study), followed by the time period, then the main observation about women's enrollment trends. This creates the most natural and academically appropriate sentence structure -> correct
