Concept:
The composition and membership caps for the Lok Sabha (the Lower House of Parliament) are governed by Article 81 of the Constitution of India.
Step 1: Tracking constitutional amendments to Lok Sabha membership.
Originally, the maximum structural ceiling of the house was set at 552 members:
• up to 530 members representing the States.
• up to 20 members representing the Union Territories.
• 2 members nominated from the Anglo-Indian community by the President under Article 331.
Step 2: Factoring in the 104th Constitutional Amendment Act.
The 104th Constitutional Amendment Act, 2019 discontinued the reservation and nomination of the 2 Anglo-Indian members. As a result, the maximum allowable strength of the Lok Sabha was reduced from 552 to 550 members (530 from States + 20 from UTs).
Step 3: Differentiating current operational vs. maximum strength.
While the *actual* filled operational seats sit around 543 members, the *maximum permitted strength* allowed by the Constitution is 550. This makes Option (C) the correct choice.
