Explanation:

The Rajya Sabha is a permanent body and unlike the Lok Sabha, it cannot be dissolved at any time. Each member of the Rajaya Sabha serves for a term of six years. But one third of its members retire at the expiration of every two years. The Vice-President of India is the ex-officio Chairman of the Rajya Sabha while the Lok Sabha has a five-year term, and is subject to dissolution at the end of its term. The Lower House can be dissolved earlier by the President on the advice of the Prime Minister
