Explanation: Uttarakhand, a state in northern India, has a unique administrative setup that includes different capitals for different seasons. This arrangement is primarily due to the climatic conditions of the region, which vary significantly between summer and winter.
Dehradun, the correct answer, is the summer capital of Uttarakhand. It is also the administrative capital of the state. Dehradun is located in the Doon Valley and is known for its pleasant climate, especially during the summer months. The city's cooler temperatures and favorable weather conditions make it an ideal location for the state government to conduct its administrative activities during the summer season.
Gairsain, on the other hand, is the winter capital of Uttarakhand. It is located in the Pithoragarh district and is situated at a higher altitude, which makes it cooler during the winter months. The state government shifts its administrative activities to Gairsain during the winter to avoid the harsh cold conditions that can be experienced in Dehradun.
It is important to note that this dual capital system is a unique feature of Uttarakhand's administrative structure. The state government operates from Dehradun during the summer and from Gairsain during the winter, ensuring that the administrative activities are conducted in a climate-appropriate environment.
Meerut and Lucknow, the other options provided, are not capitals of Uttarakhand. Meerut is a city in Uttar Pradesh, and Lucknow is the capital of Uttar Pradesh. These options might be chosen by students who are not familiar with the geography and administrative setup of Uttarakhand.
In summary, Dehradun is the summer capital of Uttarakhand due to its favorable climatic conditions during the summer months, making it the correct answer to the question. Understanding the unique administrative setup of Uttarakhand, including the reasons behind the dual capital system, is crucial for comprehending the state's governance structure.
