MRTP ACT came into force on:

5th September, 1966
3rd April, 1964
1st June, 1970
10th June, 1982 E. 25th December, 1988

The correct answer is: A. 5th September, 1966.

The Monopolies and Restrictive Trade Practices Act (MRTP Act) is an Indian law that was enacted in 1966. The Act was designed to prevent monopolies and restrictive trade practices that could harm the interests of consumers and businesses. The Act was amended in 1991 and 2002.

The MRTP Act prohibits certain types of agreements, such as agreements that fix prices, limit production, or divide markets. The Act also prohibits certain types of practices, such as abuse of dominant position and unfair trade practices.

The MRTP Act is enforced by the Competition Commission of India (CCI). The CCI is an independent body that is responsible for investigating and taking action against violations of the MRTP Act.

The MRTP Act has been criticized for being too complex and for not being effective in preventing monopolies and restrictive trade practices. However, the Act has also been praised for its role in promoting competition and protecting consumers.

The other options are incorrect because they are not the dates on which the MRTP Act came into force.
