The correct answer is Option B (Chinook).

Key Points:
• Chinook Local Winds ('Snow Eater'):
• Nature and Location: Chinook is a warm, dry, katabatic (foehn-type) local wind blowing down the eastern leeward slopes of the Rocky Mountains in North America (USA and Canada) during winter and early spring.
• 'Snow Eater' Epithet: As the descending air compresses adiabatically, it warms up rapidly (rising temperatures by 15°C to 20°C in a matter of hours), which rapidly melts and sublimates thick winter snow covers. In the Native American language, *Chinook* literally translates to "Snow Eater".
• Economic Benefit: It clears snow from winter pastures, opening up green grazing lands for cattle ranchers.
• *Fohn* is the European equivalent in the Alps; *Andhi* is a North Indian dust storm; *Berg* is a South African katabatic wind.
• Key Takeaway: Chinook is a warm, dry wind on the eastern Rocky Mountains known as the 'Snow eater' for melting winter snow.
