The correct answer is (b), Liberalisation of economy.
Liberalisation of economy is a process of reducing government control over the economy and allowing free market forces to operate. This can lead to increased economic growth, but it can also lead to increased inequality. This is because the benefits of economic growth are not always evenly distributed. Those who are already wealthy are often able to take advantage of new opportunities and increase their wealth, while those who are poor may not be able to benefit from the same opportunities.
Minimum-Needs Programme (MNP) is a government programme that aims to provide basic necessities such as food, education, and healthcare to the poor. This can help to reduce inequality by ensuring that everyone has access to basic necessities.
Taxation is a government policy that can be used to redistribute wealth. By taxing the wealthy more heavily and using the revenue to fund social programs, the government can help to reduce inequality.
Land reforms are government policies that aim to redistribute land ownership. This can help to reduce inequality by giving poor people access to land, which they can then use to generate income.
In conclusion, the correct answer is (b), Liberalisation of economy. This is because liberalisation of economy can lead to increased inequality, while the other options can help to reduce inequality.
