Explanation:

Only statement 2 is correct.

Rajya Sabha is a permanent House and cannot be dissolved. To ensure continuity, one-third of its members retire after every second year, under Article 83(1) of the Constitution, and “biennial elections” are held to fill these vacancies. The term of a member is six years.

Vacancies arising due to resignation, death or disqualification are filled up through bypolls, and those elected serve out the remainder of their predecessors’ term.

Any Bill, barring those designated as Money Bills by the Lok Sabha Speaker, needs the assent of the second chamber to become law.
