Concept:The term refers to formally ending a parliamentary session without dissolving the legislature itself.
Explanation:Prorogation is the formal ending of a session of parliament by the head of state or other constituted authority.
It ends the current sitting period but does not dissolve the parliament or terminate its existence.
Adjournment is only a temporary suspension of a sitting to a later time or date.
Recess is a short break within a session, not the discontinuation of the session.
Postponement simply means delaying proceedings to another time.
Among these, only prorogation directly matches the action described in the question.
