  3. CI - E, II - B, III - D, IV - CCorrect
  4. DI - E, II - A, III - C, IV - D

Explanation

The correct option is C based on the following geographical principles: I matches with E: Chennai is closer to the Equator than Calcutta. Its lower latitude makes it warmer throughout the year compared to Calcutta. II matches with B: Snowfall in the Himalayas during winter causes cold waves to move towards the Indo-Gangetic plains, significantly lowering temperatures in North India. III matches with D: Rainfall in the northern plains of India is primarily brought by the Bay of Bengal branch of the monsoon. As these winds move inland from West Bengal towards Punjab, they lose moisture, leading to a decrease in rainfall. IV matches with C: Winter rainfall in Northwest India is caused by Western Disturbances, which are shallow cyclonic depressions originating from the Mediterranean Sea. Therefore, the matching sequence is I-E, II-B, III-D, and IV-C.
