Which Indian freedom fighter is popularly known as “Punjab Kesari”?

Introduction / Context:
This question belongs to Indian history and the national freedom movement. Many leaders were given honorific titles that reflected their contribution, region and personality. Punjab Kesari, meaning Lion of Punjab, is one such title associated with a prominent nationalist leader who played a key role in the struggle against colonial rule.

Given Data / Assumptions:

• The title under consideration is Punjab Kesari.
• Four well known figures from Indian public life are provided as options.
• Only one of them is correctly associated with this particular title.

Concept / Approach:
Lala Lajpat Rai, a leading figure in the Indian independence movement and member of the Lal Bal Pal trio, was popularly called Punjab Kesari due to his fearless leadership and origin from Punjab. The other options represent important personalities but carry different roles or titles. Remembering the correct pairing between leader and honorific helps in getting the answer right.

Step-by-Step Solution:
Step 1: Identify which of the names provided were directly linked with Punjab during the freedom movement. Step 2: Recall that Lala Lajpat Rai was a leading nationalist from Punjab and a strong voice against British rule. Step 3: Remember that he came to be known as Punjab Kesari because of his courage and oratory. Step 4: Note that Bhagat Singh, though a revolutionary from Punjab, is usually known by his own name rather than this specific title. Step 5: Select Lala Lajpat Rai as the correct answer.

Verification / Alternative check:
History textbooks and biographies frequently refer to Lala Lajpat Rai as Punjab Kesari, highlighting his leadership in protests such as the demonstrations against the Simon Commission. There is no similar consistent use of this title for Bhagat Singh, Dadasaheb Phalke or Bal Gangadhar Tilak, who have different identities and contributions. This repeated association in multiple reliable sources confirms the answer.

Why Other Options Are Wrong:
Bhagat Singh: A legendary revolutionary from Punjab, but usually not addressed by the title Punjab Kesari in historical literature.
Dadasaheb Phalke: Known as the father of Indian cinema, not a main political leader of the freedom movement from Punjab.
Bal Gangadhar Tilak: A prominent leader from Maharashtra, often called Lokmanya Tilak, not Punjab Kesari.

Common Pitfalls:
Candidates may think of Bhagat Singh first when they see the word Punjab due to his strong association with that region. However, titles in history questions are specific and must match exact references. Careful revision of famous honorifics such as Punjab Kesari, Frontier Gandhi or Netaji helps avoid confusion in such items.

Final Answer:
The freedom fighter popularly known as Punjab Kesari is Lala Lajpat Rai.
