Option 3 is the correct matching because:

I-Chennai is warmer than Calcutta: (E) is correct because temperature generally increases as we move from higher to lower latitude. Chennai being closer to the equator (lower latitude) is warmer than Calcutta which is situated at a higher latitude.

II- Snowfall in Himalayas: (B) is correct because altitude plays a key role in temperature decrease, leading to snowfall in higher areas like Himalayas.

III- Rainfall decreases from Western West Bengal to Punjab: (D) is correct because the further an area is from the sea, the less rainfall it receives. This effect is known as continentality or the continental effect. So, rainfall decreases from Western West Bengal to Punjab because Punjab is located further from the sea compared to West Bengal.

IV- Sutlej-Ganga plain gets some rain in winter: (C) is correct because the region gets some rains from western disturbances, a type of low-pressure system that forms over the Mediterranean region and moves eastwards towards India, causing winter rainfall in the northwestern parts of India.
