The highest rainfall in India occurs in:

The correct answer is option 'A', which states that the highest rainfall in India occurs in the Western Ghats, Himalayan Region, and Meghalaya.

Explanation:

India is a vast country with diverse geographical features, and as a result, the distribution of rainfall is not uniform across the country. Different regions in India experience different levels of rainfall. The highest rainfall in India is observed in the Western Ghats, Himalayan Region, and Meghalaya. Let us understand why these regions receive the highest rainfall.

Western Ghats:
The Western Ghats are a mountain range that runs parallel to the western coast of India. These mountains act as a barrier to the moisture-laden winds coming from the Arabian Sea. As the winds hit the Western Ghats, they are forced to rise, leading to the formation of clouds and subsequent rainfall. The Western Ghats receive heavy rainfall due to the orographic effect, which results in the highest rainfall in India.

Himalayan Region:
The Himalayan region, which includes states like Uttarakhand, Himachal Pradesh, and parts of Jammu and Kashmir, experiences high rainfall due to several factors. The Himalayas act as a barrier to the moisture-laden winds from the Bay of Bengal, causing them to rise and condense into clouds. Additionally, the Himalayan region is also influenced by the monsoon winds, which bring heavy rainfall to these areas.

Meghalaya:
Meghalaya, which literally translates to "the abode of clouds," is one of the wettest places on Earth. It is located in the northeastern part of India and receives heavy rainfall due to its geographical location. The state is situated on the windward side of the Khasi Hills, which causes the moisture-laden winds from the Bay of Bengal to rise and condense into clouds, resulting in abundant rainfall.

Conclusion:

In conclusion, the highest rainfall in India occurs in the Western Ghats, Himalayan Region, and Meghalaya. These regions receive heavy rainfall due to factors such as the orographic effect, the presence of mountain ranges, and the influence of monsoon winds. This distribution of rainfall plays a crucial role in shaping the climate, vegetation, and overall landscape of these regions.
