Explanations:
Mizoram is a state located in the northeastern part of India. It is one of the smaller states in the country, both in terms of population and area. The area of Mizoram is approximately 21,087 square kilometers, which places it at the $25^{th}$ rank among all the states and union territories of India in terms of area. This ranking is based on the total land area of the state, which is a significant factor in determining the size of a state or union territory.
Understanding the area rank of Mizoram is important for students preparing for competitive examinations such as the UPSC, SSC, Bank PO, and State PSC, where questions on the geographical knowledge of Indian states and union territories are common. The area rank of a state can provide insights into its geographical characteristics, such as its landscape, climate, and potential for agricultural and industrial development.
It is important to note that the area rank of a state does not necessarily correlate with its population rank or other rankings. For example, Mizoram may have a different rank when considering population or economic indicators. Therefore, it is crucial to understand the specific context in which the ranking is being considered.
In the context of this question, the correct answer is that Mizoram is the $25^{th}$ largest state in India in terms of area. This ranking is based on the total land area of the state, which is a key factor in determining the size of a state or union territory. Understanding such rankings is essential for students preparing for competitive examinations and for those interested in the geographical and administrative divisions of India.
