The correct option is D Zhou
Confucius lived during the rule of a dynasty called the Zhou dynasty. It was a time of political struggle, moral chaos, and intellectual conflict. Confucius was pained by this degradation and thought of reforming society. He thought of reviving the traditional way of society and instill a system of social behaviour of the people. He laid down moral and social norms for individuals and communities which came to be known as Confucianism in later centuries.
