Correct Option (B)
Statements II, III, and IV accurately describe the 'Roaring Forties'. These are strong westerly winds found in the Southern Hemisphere, typically between latitudes 40° and 50° South. Their strength and constancy are attributed to the lack of significant landmasses to obstruct their flow. Their general direction is from the northwest to the east. The weather associated with these winds often includes overcast skies, precipitation, and generally rough conditions due to their intensity and oceanic origin.
Incorrect Options:
Statement I is incorrect because the 'Roaring Forties' primarily blow in the Southern Hemisphere. While strong westerly winds exist in the Northern Hemisphere, they are significantly disrupted by large landmasses and are not as consistent or globally recognized by the term 'Roaring Forties'. Therefore, they do not blow uninterrupted in both hemispheres with the same characteristics.
