In legal research methodology, 'LITERATURE REVIEW' serves to:

1. LITERATURE REVIEW serves multiple critical functions: 2. (i) SURVEY existing scholarship — what has been written on the topic and related topics; 3. (ii) IDENTIFY GAPS — what has NOT been adequately addressed; 4. (iii) SITUATE research within academic debates — building on or challenging existing work; 5. (iv) AVOID DUPLICATION — ensure originality; 6. (v) IDENTIFY METHODOLOGIES — how others have approached similar questions; 7. (vi) Build CONCEPTUAL FRAMEWORK — theoretical lenses, key concepts. 8. Two types: (a) NARRATIVE review (qualitative synthesis); (b) SYSTEMATIC review (comprehensive, predefined criteria, often used in evidence-based research). 9. Hence option B is correct. _Source: Legal Research Methodology + Jurisprudence — Research methodology_
