{'rainfall': [4, 1, 7, 3], 'west monsoons': [0, 0, 1, 0], 'monsoon': [1, 0, 2, 1], 'rainy season': [3, 0, 2, 3], 'orography': [0, 0, 2, 0], 'cyclones': [1, 0, 1, 1], 'distribution': [0, 0, 1, 0], 'coromandel coast': [3, 0, 1, 4], 'india': [8, 1, 7, 13]}

Option 1 states that the duration of the monsoon rainy season in India decreases from south to north and from east to west. This statement is correct. In general, the monsoon season starts earlier and lasts longer in the southern parts of India compared to the northern parts. Similarly, the duration of the monsoon season is longer in the eastern regions compared to the western regions.

Option 2 states that the distribution of rainfall received from the southwest monsoon in India is greatly influenced by the relief or orography. This statement is also correct. The presence of mountains and other topographical features can affect the distribution of rainfall. For example, the Western Ghats act as a barrier, causing heavy rainfall on the windward side and creating a rain shadow region on the leeward side.

Option 3 states that the bulk of the rainfall on the Coromandel Coast is derived from depressions and cyclones. This statement is correct as well. The Coromandel Coast, on the eastern side of the Indian subcontinent, experiences heavy rainfall due to the presence of cyclonic activity in the Bay of Bengal.

Therefore, all three statements are correct, and the correct answer is option 4.
