Arranging the sequence correctly for Etc. Clinical assessment of their requirement and doses:

The correct chronological order is Option 3: (A), (B), (D), (C).

Correct option: (3) (A), (B), (D), (C)

• Porcine Stress Syndrome (PSS): In swine carrying the halothane gene (RYR1 mutation in the ryanodine receptor), physical transportation, loading, or environmental crowding triggers Porcine Stress Syndrome (malignant hyperthermia).
• Pathophysiology: Uncontrolled calcium release from the sarcoplasmic reticulum triggers hypermetabolic skeletal muscle contraction, malignant hyperthermia ($\gt 42^\circ\text{C}$), severe lactic acidosis, muscle rigidity, and sudden acute cardiovascular collapse.

Correct option: (3) Porcine stress syndrome (PSS).

• Equine Keratomycosis: Mycotic keratitis in horses is a serious, vision-threatening ocular condition frequently caused by opportunistic environmental filamentous fungi, primarily Aspergillus flavus, Aspergillus fumigatus, and Fusarium species.
• Pathogenesis: Minor corneal microtrauma allows fungal hyphae to invade the corneal stroma, elaborating collagenases and proteases that produce stromal melting, deep corneal ulceration, and hypopyon.

Correct option: (2) Aspergillus flavus
