The correct answer is b) Kuttanad.
Kuttanad is a region in the state of Kerala, India. It is a low-lying area that is prone to water-logging. The main reason for water-logging in Kuttanad is the high rainfall in the region. The average annual rainfall in Kuttanad is about 3,000 mm. The high rainfall causes the rivers in the region to overflow, which leads to water-logging in the low-lying areas.
Another reason for water-logging in Kuttanad is the construction of dams and canals in the region. These dams and canals have changed the natural flow of water in the region, which has led to water-logging in some areas.
Water-logging can have a number of negative impacts on the environment and the people living in the region. It can lead to the loss of crops, the spread of diseases, and the damage of infrastructure.
The government of Kerala has taken a number of measures to address the problem of water-logging in Kuttanad. These measures include the construction of drainage systems, the raising of the embankments of the rivers, and the planting of trees.
Despite these measures, the problem of water-logging in Kuttanad continues to be a major challenge. The government of Kerala needs to take further measures to address this problem.
The other options are incorrect because:
a) Palakkad is a district in the state of Kerala, India. It is not a low-lying area and is not prone to water-logging.
c) Wayanad is a district in the state of Kerala, India. It is a high-lying area and is not prone to water-logging.
d) Idukki is a district in the state of Kerala, India. It is a high-lying area and is not prone to water-logging.
