Concept:
Matching questions test conceptual clarity of legal definitions.
Step 1:
Bail refers to temporary release of an accused on security → i-e.
Arrest is lawful deprivation of liberty → ii-b.
Summons is an order to appear before court → iii-a.
FIR is the first information report of crime → iv-d.
Step 2: Matching gives i-e, ii-b, iii-a, iv-d.
