The correct answer is: B) Landslides.
The Western Ghats are a mountain range in India that are prone to landslides. Improper land use practices, such as deforestation and mining, can increase the risk of landslides. Deforestation can destabilize the slopes of mountains, making them more likely to collapse. Mining can also destabilize slopes, and can also pollute water supplies, which can lead to landslides.
Tsunamis are large waves that are caused by earthquakes or volcanic eruptions. Earthquakes are not common in the Western Ghats, and volcanic eruptions are even less common. Therefore, tsunamis are not a major threat to the Western Ghats.
Earthquakes are caused by the movement of tectonic plates. The Western Ghats are located on the boundary between the Indian and Eurasian tectonic plates, so earthquakes are a possibility. However, earthquakes are not as common in the Western Ghats as they are in other parts of India.
Droughts are periods of time with little or no rain. The Western Ghats are not as prone to droughts as other parts of India. This is because the Western Ghats receive a lot of rainfall from the monsoons.
In conclusion, the correct answer is: B) Landslides.
