{'arabian sea': [2, 0, 3, 3], 'climate': [2, 0, 2, 2], 'western disturbances': [0, 0, 0, 1], 'caspian sea': [1, 0, 0, 1], 'baltic sea': [1, 0, 0, 1], 'mediterranean sea': [2, 0, 1, 3], 'india': [8, 1, 7, 13]}

The correct answer is option 4, the Mediterranean Sea. Western disturbances are weather systems that bring rainfall to northwestern parts of India, particularly during the winter season. These disturbances are a result of the interaction between the tropical easterlies and the mid-latitude westerlies.

The Mediterranean Sea is an important source region for these disturbances. The sea provides the necessary moisture and instability required for the formation of these weather systems. As the disturbances move eastward, they influence the weather patterns over the Indian subcontinent. They bring rainfall and snowfall to areas like Jammu and Kashmir, Himachal Pradesh, Punjab, and parts of Rajasthan, helping to offset the aridity of these regions.

The other options provided - Arabian Sea, Baltic Sea, and Caspian Sea - are not directly associated with the origin of Western disturbances in India. While the Arabian Sea does have an influence on the monsoon rains in India, it is not the origin of Western disturbances. Baltic Sea and Caspian Sea, on the other hand, are not relevant in the context of Western disturbances in India.
