1934 is the answer that matches the Bihar-specific fact asked in the question. The wording of the question specifically requires the association represented by 1934. Option A (1929) is incorrect because it does not match the specific person, district, place, institution, event or factual association asked in the question. Option C (1938) is incorrect because it does not match the specific person, district, place, institution, event or factual association asked in the question. Option D (1936) is incorrect because it does not match the specific person, district, place, institution, event or factual association asked in the question. The Indian National Congress session of 1934 was held in Patna (Haripura was 1938 — different session). The Patna INC session of 1934 was presided over by Rajendra Prasad. Subhas Chandra Bose was elected President of the Indian National Congress at the Haripura session in 1938 and was re-elected at the Tripuri session in 1939, where he defeated Gandhi's candidate Pattabhi Sitaramayya. The question as framed links Patna with a notable INC session. The 1934 Patna session was significant as it came during a crucial phase of the independence movement after the Civil Disobedience Movement was suspended. The 1929 session was the Lahore session where Purna Swaraj (complete independence) was declared under Jawaharlal Nehru. The 1936 session was held at Lucknow under Jawaharlal Nehru. Understanding which INC sessions were held in Bihar (Patna) is important for exam preparation, as Patna hosted several significant Congress sessions during the freedom struggle era.
