Option 1 -> "advise before" and "work from" don't form correct collocations in this context.
Option 2 -> "advise for" is grammatically incorrect; we don't use "advise for" in English.
Option 3 -> "advise against" means to recommend not doing something, and "during term-time" correctly indicates throughout the academic term period.
Option 4 -> "advise over" is not a proper collocation, and "work at term-time" is incorrect.
Hence, Option 3: against; during -> The sentence expresses a contrast where universities recommend that students NOT have jobs ("advise against"), but financial pressures force many students to work throughout the academic term ("during term-time"). Both prepositions form correct collocations and create logical meaning -> correct
