• Genome Assembly Approaches:
• De novo Assembly $\to$ (II): Assembling short or long reads into contigs and scaffolds from scratch without relying on any prior reference genome.
• Comparative Assembly $\to$ (I): Guiding the assembly and scaffolding of a target genome using a reference genome from a closely related species.
• Reference-based Assembly $\to$ (IV): Aligning reads directly to an existing reference genome of the same species (e.g., resequencing studies).
• Hybrid Assembly $\to$ (III): Integrating sequencing data from complementary sequencing platforms (e.g., highly accurate Illumina short reads combined with PacBio/Nanopore long reads).
• Matching Result: (A) - (II), (B) - (I), (C) - (IV), (D) - (III) (Option 2).

Correct option: (2) (A) - (II), (B) - (1), (C) - (1), (D) - (Ill)

• Biomedical Literature Databases:
• MEDLINE is the National Library of Medicine's (NLM) premier bibliographic and literature database, containing millions of references and abstracts to biomedical and life sciences journal articles (searchable via PubMed).
• Other Databases Listed:
• ChEBI: Chemical Entities of Biological Interest (chemical database).
• MIAME: Minimum Information About a Microarray Experiment (reporting standard).
• DALI: Protein structural alignment tool/database.
• Conclusion: MEDLINE is a literature database (Option 4).

Correct option: (4) MEDLINE
