Who served as the first Speaker of the Lok Sabha after the Constitution of India came into force?

Introduction / Context:
The Speaker of the Lok Sabha occupies a central place in the Indian parliamentary system. The first Speaker set important conventions and practices for how the lower house would function in independent India. Knowing the name of this first office holder is a common general knowledge and polity question. It helps connect constitutional history with the institutions that operate today.

Given Data / Assumptions:

• The question asks about the first Speaker of the Lok Sabha after the Constitution came into effect.
• Several names of later Speakers and senior parliamentarians are included as options.
• We assume the context is the first Lok Sabha formed after the general elections of the early nineteen fifties.

Concept / Approach:
Ganesh Vasudev Mavalankar, commonly known as G V Mavalankar, was the first Speaker of the Lok Sabha. He had earlier served as the Speaker of the Central Legislative Assembly under British rule. After India adopted the Constitution and held the first general elections, he was chosen to preside over the Lok Sabha, helping to shape many early parliamentary traditions. Other names in the options served as Speakers later or occupied other positions but not as the first Speaker.

Step-by-Step Solution:
Step 1: Recall that G V Mavalankar is widely recognised as the first Speaker of the Lok Sabha.Step 2: Note that M A Ayyangar succeeded him and is therefore not the first.Step 3: Recognise that G S Dhillon and Hukum Singh served in later decades and cannot be the first Speaker.Step 4: Sumitra Mahajan is a recent Speaker and clearly from a much later period.Step 5: Based on this historical ordering, select G V Mavalankar as the correct answer.

Verification / Alternative check:
A quick verification can be done by recalling that the first Lok Sabha was formed after the general elections of 1951 to 1952. Most standard polity books present a chronological list of Speakers, starting with G V Mavalankar, followed by M A Ayyangar. Many exam oriented summaries of Parliament also highlight Mavalankar as the first and Sumitra Mahajan as one of the more recent Speakers, which confirms the relative positions of these leaders.

Why Other Options Are Wrong:
M A Ayyangar was the second Speaker of the Lok Sabha, not the first. G S Dhillon served as Speaker later and is associated with a different period of parliamentary history. Hukum Singh was a Deputy Speaker of the Lok Sabha, not the first Speaker. Sumitra Mahajan is a contemporary leader who served as Speaker much later. Because the question specifically asks for the first Speaker, none of these names satisfy the requirement.

Common Pitfalls:
Some learners confuse the order of early Speakers, especially between G V Mavalankar and M A Ayyangar. Others simply remember the names of recent Speakers and overlook those from the early decades. A helpful method is to mentally pair G V Mavalankar with the birth of the Republic and the first Lok Sabha, and to see him as the starting point of the line of Speakers in independent India.

Final Answer:
G V Mavalankar
