The concept of Dyarchy was introduced as part of British administrative reforms in India.
Step 1: Understanding the meaning of Dyarchy.
The term “Dyarchy” means:
\[
\text{Dual Government}
\]
Under this system, provincial subjects were divided into two categories:
• Reserved Subjects
• Transferred Subjects
Reserved subjects remained under the control of the Governor and executive council, while transferred subjects were handled by Indian ministers.
Step 2: Identifying the Act associated with Dyarchy.
The system of Dyarchy was introduced by the:
\[
\text{Government of India Act, 1919}
\]
This Act is also known as:
\[
\text{Montagu-Chelmsford Reforms}
\]
The reforms aimed to provide limited self-government to Indians.
Step 3: Checking the remaining options carefully.
• Government of India Act, 1909 introduced separate electorates but not Dyarchy.
• Government of India Act, 1935 abolished Dyarchy in provinces and introduced provincial autonomy.
• Indian Councils Act, 1892 expanded legislative councils but did not introduce Dyarchy.
Hence, only the Government of India Act, 1919 introduced Dyarchy.
Therefore, the correct answer is:
\[
\boxed{(B)\ \text{Government of India Act, 1919}}
\]
