Consider the following statements:   1) The winds which blow between 30 degrees N and 60 degrees S latitudes throughout the year are known as westerlies. 2) The moist air masses that cause winter rams in North-Western region of India are part of westerlies. Which of the statements given above is/are correct?

Statement 2 is correct and statement 1 is not, so the answer is B.

Statement 1 is wrong as written. Westerlies occur in both hemispheres, roughly between 30 and 60 degrees latitude: 30-60 N and 30-60 S. The statement joins 30 N to 60 S, which spans the equator and the tropical trade wind belt. These winds are persistent, but they shift north and south with the seasons, so "throughout the year" is also loose.

Statement 2 is correct. Winter rain in north-western India (Punjab, Haryana, J&K, Himachal, Uttarakhand) is brought by Western Disturbances. These are extratropical cyclonic systems carried eastward by the westerlies, originating over the Mediterranean and Caspian region. They matter for rabi crops like wheat and for Himalayan snowfall.

Core concept: planetary wind belts (Ferrel cell and westerlies) and the extratropical disturbances they carry. Mains link: Western Disturbances and their role in rabi agriculture and water security in north India.

Trap: aspirants see the word "westerlies" and assume the whole statement is right, missing the latitude error in statement 1 because the wording looks like a textbook definition.
