The Department of Official Language, also known as Raj Bhasha Vibhag, comes under the Ministry of Home Affairs. This department is responsible for the implementation of the Official Language Policy of the Government of India.
Option 1, the Ministry of Culture, is not the correct answer because the Department of Official Language does not fall under this ministry. The Ministry of Culture is primarily responsible for the preservation, promotion, and development of various art forms, cultural heritage, and languages in India.
Option 3, the Ministry of Human Resource Development, is also not the correct answer. This ministry is responsible for the development and implementation of policies related to education and skill development in India.
Option 4, the Ministry of Information and Broadcasting, is again not the correct answer. This ministry is responsible for the formulation and implementation of policies related to media and information dissemination in India.
Therefore, the correct answer is option 2, the Ministry of Home Affairs. This ministry is responsible for maintaining internal security, law enforcement, and public administration in India, including the Department of Official Language.
