Explanations:The question asks for the incorrect pair of state and capital. To answer this, it is essential to know the capitals of the states mentioned in the options. The states and their capitals are as follows:
1. Tripura: The capital of Tripura is Agartala. This is a well-known fact and is correctly paired in the options.
2. West Bengal: The capital of West Bengal is Kolkata. This is also a well-known fact and is correctly paired in the options.
3. Sikkim: The capital of Sikkim is Gangtok. This is the key piece of information that makes the question challenging. Shillong, which is mentioned in the incorrect option, is actually the capital of Meghalaya, not Sikkim. This confusion can arise because both Sikkim and Meghalaya are located in the northeastern part of India, and students might mix up the capitals of these states.
4. The option "All of them are correctly matched" is incorrect because the pair "Sikkim: Shillong" is not correct. Therefore, the correct answer is the option that states "Sikkim: Shillong" as the incorrect pair.
It is important to note that geographical knowledge, especially regarding state capitals, is crucial for various competitive exams and general knowledge tests. Students should familiarize themselves with the capitals of all states in India to avoid such errors. Additionally, it is helpful to use mnemonics or other memory aids to remember these capitals, especially for states that are less frequently discussed in everyday contexts.
