पर्यायी उत्तरे :

The correct answer is Option B ((A) and (B) both are true.).

Key Points:
• Dr. B.R. Ambedkar and the National Language Debate in the Constituent Assembly:
• Assertion (A): In September 1949, during the heated Hindi versus Hindustani / regional languages linguistic debate in the Constituent Assembly, Dr. B. R. Ambedkar formally sponsored an amendment proposing that Sanskrit be made an official / national language of the Indian Union.
• Reason (B): Dr. Ambedkar, a deep scholar of Indology and comparative linguistics, maintained that Sanskrit is the grammatical and lexical mother of most Indian languages and holds the repository of ancient India's immense contributions to philosophy, literature, science, and jurisprudence. A mastery of Sanskrit was essential to objectively decipher ancient Indian intellectual thought.
• Hence, both Assertion (A) and Reason (B) are historically accurate and valid.
• Key Takeaway: Dr. Ambedkar proposed Sanskrit as the national language in the Constituent Assembly to preserve and understand ancient Indian heritage.
