The correct answer is option 3, which states that the minimum age limit for the membership of the Vidhan Parishad is 30 years. It is important to note that the Vidhan Parishad, also known as the Legislative Council, is the upper house of the state legislature in some states of India. Members of the Vidhan Parishad are usually elected by the members of the Legislative Assembly, local governments, and other bodies. The minimum age requirement of 30 years ensures that candidates have reached a certain level of maturity and experience before they can become members of the Vidhan Parishad. This requirement helps in ensuring that individuals who are elected to this position are capable of handling the responsibilities and making informed decisions regarding state matters.
