The correct answer is option-2, 1772. The office of District Collector was created in 1772. This role was introduced during the British colonial rule in India. The purpose of the District Collector is to administer and manage the revenue and general administration of a district. The District Collector holds significant responsibilities such as tax collection, maintenance of law and order, overseeing infrastructure development, and implementation of government policies at the district level. This administrative position continues to exist in India even after gaining independence. It is important to note that the other options (option-1, option-3, and option-4) are incorrect and do not represent the accurate year in which the office of District Collector was established.
