Concept:This slogan is a famous distributive principle associated with Marxist ideology.
Explanation:The principle means that every person should work and contribute to society according to their ability.
In return, every person should receive goods and services according to their needs.
This idea is central to a communist society, where private ownership is removed and wealth is shared equally.
It stands against capitalist systems, where distribution is based on profit and ability to pay.
Karl Marx popularized this phrase in his 1875 work, the "Critique of the Gotha Programme".
It is not from "The Communist Manifesto", which was published earlier in 1848.
Therefore, the principle belongs to communism rather than socialism, capitalism, or communalism.
Answer:A. Communism.
