In Rajya Sabha, the President of India nominates 12 members.

Explanation:
The Rajya Sabha, also known as the Council of States, is the upper house of the Parliament of India. It consists of a total of 245 members, out of which 233 members are elected by the eligible members of the State Legislative Assemblies and the remaining 12 members are nominated by the President of India.

These nominated members are chosen by the President based on their expertise and contribution to various fields such as literature, science, art, and social service. The purpose of nominating members is to ensure representation of distinguished individuals who have made significant contributions to society and can bring their expertise to the legislative process.

The nominated members serve a term of six years. Unlike the elected members, they do not represent any particular state or union territory. However, they have the same rights and privileges as the elected members and can actively participate in the proceedings of the Rajya Sabha.

The nomination of members by the President helps in maintaining the diversity and expertise in the Rajya Sabha. It allows for the inclusion of individuals who may not have been elected through the regular electoral process but possess valuable knowledge and experience in their respective fields. This contributes to the overall effectiveness and diversity of the legislative body.

In conclusion, the President of India nominates 12 members to the Rajya Sabha. These members are chosen based on their expertise and contribution to various fields, and they serve a term of six years.
