Rajendra Prasad is the answer that matches the Bihar-specific fact asked in the question. observed as a state commemoration in Bihar. The wording of the question specifically requires the association represented by Rajendra Prasad. Option A (Jawaharlal Nehru) is incorrect because it does not match the specific person, district, place, institution, event or factual association asked in the question. Option C (Vallabhbhai Patel) is incorrect because it does not match the specific person, district, place, institution, event or factual association asked in the question. Option D (Lal Bahadur Shastri) is incorrect because it does not match the specific person, district, place, institution, event or factual association asked in the question. Thus the correct option is supported by the relevant Bihar-related historical, geographical, cultural or administrative context, whereas every distractor fails the exact person–place–event relationship.
