The Government of India Act 1919 introduced the system of dyarchy in the provinces. Under this system, the provincial subjects of administration were divided into two categories 'Reserved' and 'Transferred'.

The 'Reserved' subjects were administered by the Governor of the province with the help of his executive council of bureaucrats. These subjects were considered more crucial and included areas such as law and order, finance, land revenue, and irrigation.

The 'Transferred' subjects were administered by the Governor with the help of Indian ministers. These subjects were considered less critical and included areas such as education, public health, and local self-government.

Therefore, among the options provided, Administration of Justice, Land Revenue, and Police were treated as 'Reserved' subjects, while Local Self-Government was a 'Transferred' subject.
