The majority of Kerala’s rivers flow:

The majority of Kerala’s rivers flow from east to west. This is because the Western Ghats, a mountain range that runs along the western coast of India, blocks the flow of water from the east. The water from the Western Ghats flows down into the rivers, which then flow west towards the Arabian Sea.

Option a) is incorrect because the majority of Kerala’s rivers do not flow north to south. Option c) is incorrect because the majority of Kerala’s rivers do not flow west to east. Option d) is incorrect because the majority of Kerala’s rivers do not flow south to north.
