Matching the items of List I with List II for Inflammation – definitions associated with inflammatory phenomenon:

The correct combination is Option 4: (A) - (III), (B) - (V), (C)- (I), (B) - (1).

Correct option: (4) (A) - (III), (B) - (V), (C)- (I), (B) - (1)

• Complement Anaphylatoxins: Anaphylatoxins are low-molecular-weight peptide fragments released during activation of the complement cascade: C3a, C4a, and C5a.
• Biological Potency & Receptors: These fragments bind specific G-protein coupled receptors on tissue mast cells, basophils, and smooth muscle cells, triggering immediate degranulation, histamine release, smooth muscle contraction, and increased vascular permeability:
• C5a: The most potent anaphylatoxin and a powerful chemotactic factor for neutrophils and monocytes.
• C3a: Intermediate anaphylatoxin activity.
• C4a: Weakest anaphylatoxin activity.
• C2a Exclusion: C2a is a large enzymatically active fragment that complexes with C4b to form C3 convertase ($C4b2a$), NOT an anaphylatoxin.

Correct option: (3) (B), (C) and (D) only.

• Pathological Hallmark of Bovine Tuberculosis: Tuberculosis (Mycobacterium bovis, M. tuberculosis) produces the canonical caseo-calcifying granuloma (the classic tuberculous tubercle).
• Microscopic Architecture: A centrally located focus of caseous necrosis (amorphous, eosinophilic, cheesy debris) that characteristically undergoes progressive dystrophic calcification (forming basophilic calcium salt deposits), surrounded by palisades of epithelioid macrophages, multinucleated Langhans giant cells, a mantle of lymphocytes, and an outer fibrous capsule.
• Contrasting Granulomas:
• Johne's Disease: Diffuse, non-caseating, non-calcifying epithelioid granulomatous enteritis.
• Actinomycosis: Pyogranulomatous lesion with Splendore-Hoeppli phenomenon (sulfur granules) lacking caseous calcification.

Correct option: (3) Tuberculosis
