Explanations:The question is based on the concept of state capitals in India. The format "Goa: Panaji:: Bihar: ...." is a type of analogy where the first part (Goa: Panaji) establishes a relationship, and the second part (Bihar: ....) requires the identification of the corresponding element that maintains the same relationship. In this case, the relationship is that Panaji is the capital city of Goa, and the question asks for the capital city of Bihar.
India is a federal union comprising 28 states and 8 union territories, each with its own capital city. The capital city is the administrative and political center of the state, where the state government is headquartered. It is important to know the capitals of different states for various reasons, including administrative purposes, geographical knowledge, and for competitive examinations.
For the state of Bihar, the capital city is Patna. Patna is located in the eastern part of India and is one of the oldest continuously inhabited places in the world. It has a rich historical and cultural heritage and serves as the political and administrative center of Bihar. Patna is well-connected by road, rail, and air, making it a significant urban center in the region.
It is crucial to distinguish Patna from the capitals of other states to avoid confusion. For example, Itanagar is the capital of Arunachal Pradesh, and Dispur is the capital of Assam. Each state has its own unique capital, and it is important to be familiar with these capitals to correctly answer questions like the one posed.
In summary, the question tests the knowledge of state capitals in India, specifically the capital of Bihar, which is Patna. Understanding the administrative structure of states and their capitals is essential for geographical knowledge and for performing well in competitive examinations that test such information.
