Which of the following Constitutional Amendments are related to raising the number of Members of Lok Sabha to be: elected from the States?

1. The question asks which Constitutional Amendments related to raising the number of Members of Lok Sabha elected from the States. 2. The initial number of elected members from states in Lok Sabha was set based on the population as per Article 81. 3. The 7th Amendment Act, 1956, reorganized states and allotted seats, also removing the upper limit of 500 seats for states. 4. The 31st Amendment Act, 1973, increased the upper limit of elected Members of Lok Sabha from the States from 500 to 525, and reduced the limit for Union Territories from 25 to 20. This explicitly raised the number of potential members from states. 5. Let's check other options: - 6th (1956): Related to taxes on sale/purchase of goods. - 22nd (1969): Formation of Meghalaya. - 13th (1962): Formation of Nagaland. - 38th (1975): Related to Emergency provisions. - 11th (1961): Related to election of Vice-President. - 42nd (1976): Major amendments ('Mini-Constitution'), froze LS seats till 2001 based on 1971 census. 6. Therefore, the 7th and 31st Amendments are directly related to adjusting/raising the number of Lok Sabha members elected from States. 7. This corresponds to option (C).
