Which revolutionary freedom fighter threw a bomb in the Central Legislative Assembly along with Bhagat Singh in 1929?

Introduction / Context:
The incident of throwing a bomb in the Central Legislative Assembly in 1929 is one of the most famous episodes in the history of the Indian freedom struggle. The act was meant to protest against repressive laws and to make the voice of Indian revolutionaries heard. Bhagat Singh is well known for this action, but he did not act alone. This question focuses on the identity of his companion, a detail that is often asked in competitive exams on modern Indian history.

Given Data / Assumptions:

• The event took place in 1929 in the Central Legislative Assembly in Delhi.
• Bhagat Singh is already mentioned, and we need the name of the other revolutionary involved.
• Options list several well known revolutionaries such as Sukhdev, Jatin Das, Rajguru, Chandrashekhar Azad, and B K Dutt.

Concept / Approach:
On 8 April 1929, Bhagat Singh and Batukeshwar Dutt, commonly known as B K Dutt, threw bombs in the Central Legislative Assembly. The objective was not to cause mass casualties but to make a political statement, so the bombs were relatively harmless and warnings were given. After the explosion, both revolutionaries courted arrest and used the trial as a platform to publicise their cause. While Sukhdev and Rajguru were close associates of Bhagat Singh, they were involved in other actions, including the killing of Saunders, not this particular Assembly bombing.

Step-by-Step Solution:
Step 1: Recall the names associated with the Central Legislative Assembly bomb case of 1929.Step 2: Note that the duo involved was Bhagat Singh and B K Dutt.Step 3: Recognise that Sukhdev and Rajguru were involved mainly in the Lahore conspiracy and the Saunders case, not this Assembly incident.Step 4: Remember that Jatin Das is known for his hunger strike in jail and not for throwing this bomb.Step 5: Chandrashekhar Azad was a mentor and leader but did not accompany Bhagat Singh in the Assembly bombing. Therefore, B K Dutt is the correct answer.

Verification / Alternative check:
Verification can be done by reviewing the well known slogan of the Assembly bomb case, which is often quoted in history books, along with the names of Bhagat Singh and B K Dutt. Accounts of the trial and the strategy of the Hindustan Socialist Republican Association clearly mention Batukeshwar Dutt as the co accused. This cross reference from multiple historical sources confirms that B K Dutt is the right option among the names provided.

Why Other Options Are Wrong:
Sukhdev was a close associate of Bhagat Singh and was hanged along with him for the Lahore conspiracy, but he was not involved in the 1929 Assembly bomb case. Jatin Das is remembered for his long hunger strike in jail, which drew attention to the conditions of political prisoners. Rajguru took part in the killing of Saunders, again linked with the Lahore conspiracy case. Chandrashekhar Azad was a key leader and mentor of many revolutionaries, but he did not physically participate in the Assembly bombing of 1929.

Common Pitfalls:
Many learners remember the group of Bhagat Singh, Sukhdev, and Rajguru together and may wrongly pick one of those names for any related revolutionary action. Others confuse the different cases and events in which these leaders were involved. A useful method is to tie each person to one signature event: Sukhdev and Rajguru to the Saunders case, Jatin Das to the hunger strike, Chandrashekhar Azad to his final encounter in a park in Allahabad, and B K Dutt to the Assembly bomb case.

Final Answer:
B K Dutt
