The correct answer is D. None.
FDI or Foreign Direct Investment is a type of investment where a company or individual from one country invests in a company or business in another country. FDI can take many forms, such as buying shares in a company, setting up a new business, or acquiring an existing business.
India has a number of sectors that are closed to FDI, including atomic energy, railway operation, and real estate investment trusts. This means that foreign companies are not allowed to invest in these sectors.
The reasons for this vary from sector to sector. In the case of atomic energy, the government is concerned about national security and does not want foreign companies to have access to sensitive technology. In the case of railway operation, the government wants to ensure that the railways remain under Indian control. And in the case of real estate investment trusts, the government is concerned about the impact of foreign investment on the Indian real estate market.
Despite these restrictions, FDI is still a major source of investment in India. In 2019, FDI inflows into India reached a record $62 billion. This investment has helped to create jobs, boost economic growth, and improve infrastructure in India.
The government of India is gradually opening up more sectors to FDI. In recent years, the government has allowed FDI in sectors such as defense, insurance, and retail. This is likely to continue in the future, as the government looks to attract more foreign investment into India.
