Correct Option: B

Summer monsoon (May to September) experiences South Western monsoon. The Western Ghats are the first highlands of India that the SW Monsoon winds encounter. The presence of abundant highlands like the Western Ghats and the Himalayas right across the path of the SW Monsoon winds are the main cause of the substantial orographic precipitation all over the Indian subcontinent. The Western Ghats rise very abruptly from the Western Coastal Plains of the subcontinent making effective orographic barriers for the Monsoon winds.
