To become a member of the Rajya Sabha, a person should be at least 30 years old. The Rajya Sabha is the upper house of the Parliament of India, and it represents the states and Union Territories of the country. It is important to note that the age requirement for becoming a member of the Rajya Sabha is different from that of the Lok Sabha, which is the lower house of Parliament. In the Lok Sabha, the minimum age requirement is 25 years. Therefore, option 2, which states that the minimum age requirement is 30, is the correct answer. It is important for candidates aspiring to be members of the Rajya Sabha to meet this age requirement in order to be eligible for election or appointment to the position.
