The correct answer is option 3, Sikkim. This means that Sikkim is the only state represented by only one member in the Lok Sabha.
In the Indian parliamentary system, the Lok Sabha is the lower house of the Parliament and is made up of members who are elected by the people. Each state is allotted a certain number of seats in the Lok Sabha based on its population. However, there are some states, like Sikkim, that have a relatively smaller population and are therefore represented by only one member in the Lok Sabha.
Option 1, Manipur, and option 4, Tripura, are not the correct answers because both of these states have more than one member representing them in the Lok Sabha. Option 2, Meghalaya, is also not the correct answer as Meghalaya also has more than one member in the Lok Sabha.
It is important to note that the representation in the Lok Sabha is not the same as the representation in the Rajya Sabha, which is the upper house of the Parliament. The Rajya Sabha has a different system of representation, and the number of members from each state is determined differently.
