The correct answer is: a) Eastern Ghats.
Transhumance is the seasonal movement of livestock between two or more pastures. It is a traditional practice that is still practiced in many parts of the world, including Odisha. In Odisha, transhumance is mainly seen in the Eastern Ghats. The Eastern Ghats are a mountain range that runs along the eastern coast of India. The climate in the Eastern Ghats is cooler and more humid than the climate in the rest of Odisha. This makes it a good place for grazing livestock.
During the summer, the temperature in the Eastern Ghats can be very high. This makes it difficult for livestock to find enough food and water. To avoid this, herders move their livestock to higher altitudes, where the climate is cooler and there is more grass. In the winter, the temperature in the Eastern Ghats can be very low. This can make it difficult for livestock to find enough food and water. To avoid this, herders move their livestock to lower altitudes, where the climate is warmer and there is more grass.
Transhumance is a sustainable way of managing livestock. It helps to prevent overgrazing and soil erosion. It also helps to maintain the biodiversity of the region.
The other options are incorrect because:
- The Western Uplands are a dry region that is not suitable for grazing livestock.
- The Coastal Plains are a hot and humid region that is not suitable for grazing livestock.
- The Northern Plateau is a mountainous region that is not suitable for grazing livestock.
