Correct Answer: (a) Socialist
Solution:The planned economy in India was based on the socialist system. Although the Indian economy is a mixed economy, there is neither a fully capitalist economy nor a fully socialist economy. In a socialist economic system, there is social ownership of the means of production rather than individual ownership. At the same time, these means of production are not used for any individual interest, but for social and collective interests. Apart from this, equitable distribution of production and national income is done in the socialist economic system, so that human beings do not do human exploitation. In a socialist economic system, the government decides to produce different goods according to the needs of the society. According to Schumpeter, a "Socialist economy is an economy in which the means of production are controlled by the central power, where the economic activities of the society take place in the public sector rather than in the private sector".
