The basic objective of playing regulatory role by government is to:

Prevent the market structure from becoming monopolistic
Developing the small and new entrepreneurs
Promoting welfare of weaker sections of the society
All of the above

The correct answer is D. All of the above.

The government plays a regulatory role in the economy to ensure that the market is fair and competitive, and that the rights of consumers and businesses are protected. This includes preventing monopolies, developing small and new businesses, and promoting the welfare of weaker sections of society.

Monopolies are harmful to the economy because they can lead to higher prices, lower quality goods and services, and less innovation. The government regulates monopolies by breaking them up, regulating their prices, or preventing them from forming in the first place.

The government also plays a role in developing small and new businesses. This can be done through providing financial assistance, tax breaks, and other forms of support. Small businesses are important to the economy because they create jobs, drive innovation, and help to keep the economy competitive.

Finally, the government also plays a role in promoting the welfare of weaker sections of society. This can be done through providing social safety nets, such as unemployment benefits and food stamps, as well as through programs that provide education and job training. The government’s role in promoting the welfare of weaker sections of society is important because it helps to ensure that everyone has a chance to succeed in the economy.
