​In the Input- output analysis of David Easton, the inputs stand for:​

Correct option is C

The correct answer is (c) Demands and supports.

David Easton, a prominent political scientist, developed a systems theory model of politics. His Input-Output analysis treats the political system as part of a larger social system that interacts with its environment. In this model, inputs refer to the demands and supports coming from the environment (i.e., society, economy, culture) into the political system.

Demands: These are expectations and requests from individuals or groups for public policies or actions (e.g., demands for better education, infrastructure, security, etc.).

Supports: These include actions that legitimize and uphold the political system, such as voting, obeying laws, paying taxes, and showing loyalty to institutions.

These inputs are processed by the political system (government institutions), resulting in outputs (decisions, laws, policies), which then generate feedback, helping the system adjust or respond to societal changes.​

Information Booster : 

Systems Theory in political science is a framework that views political life as a complex and dynamic system, where various elements (inputs, institutions, processes, outputs, feedback) interact in a structured way. It was primarily developed by David Easton in the mid-20th century.

 Key Features​
Politics as a System
Politics is seen as a closed-loop system that interacts with the external environment (society, economy, international conditions).
​
Components of the System:

Inputs:
These are demands (e.g., for jobs, welfare, security) and supports (e.g., tax compliance, voting, political participation) from the public.
​

Political System (Conversion Process):
Government institutions (legislature, executive, bureaucracy) that convert demands into policies.

Outputs:
The decisions, laws, and policies made in response to the inputs.

Feedback:
Public response to outputs, which loops back into the system as new inputs.
​
Environment:
The broader societal context (culture, economy, demography) that shapes and influences the political system.
