The term of the Lok Sabha

The Lok Sabha’s normal life is five years, but during a proclaimed national emergency Parliament may extend its term by a law for one year at a time. This extension can be repeated for as long as the emergency continues, yet it cannot be continued beyond six months after the emergency has ceased to operate [1]. Therefore, the statement that the term “can be extended by one year at a time during the proclamation of emergency” is correct. Options asserting no extension under any circumstances, six-month increments, or two-year increments are inconsistent with the constitutional provision that extensions are for one year at a time and cease no later than six months after the emergency ends [1].
