The correct answer is option 1: 11. In Odisha, there are a total of 11 Rajya Sabha parliamentary seats. The Rajya Sabha is the upper house of the Parliament of India and represents the states and union territories. Each state is allocated a certain number of seats in the Rajya Sabha based on its population and other factors. In the case of Odisha, it has been allocated 11 seats. These seats are filled through indirect elections in which members of the Odisha Legislative Assembly participate. The Rajya Sabha plays an important role in the decision-making process and legislative functions of the Indian government.
