The correct answer is c) 2500 mm.
Kerala is a state in India that is known for its lush green forests and its heavy rainfall. The average annual rainfall in Kerala is approximately 2500 mm. This high rainfall is due to the state’s location on the Western Ghats, which are a mountain range that runs along the western coast of India. The Western Ghats are a major source of rainfall for the Indian subcontinent, and they receive an average of 2000-3000 mm of rainfall per year.
The high rainfall in Kerala is beneficial for the state’s agriculture and tourism industries. The state’s forests are home to a variety of plants and animals, and the rainfall helps to keep the forests healthy. The rainfall also helps to fill the state’s rivers and reservoirs, which are used for irrigation and drinking water.
However, the high rainfall can also be a problem. The state is prone to landslides and floods, and the heavy rains can damage crops and infrastructure. The state government has taken steps to mitigate the risks of flooding and landslides, but the high rainfall remains a challenge for the state.
The other options are incorrect because they are not the average annual rainfall in Kerala. Option a) 500 mm is too low, and option b) 1500 mm is too high. Option d) 3500 mm is closer to the correct answer, but it is still slightly too high.
