The correct answer is C. Remittances from Keralites working abroad.
Kerala is a state in India with a population of over 33 million people. It is the most literate state in India, with a literacy rate of 94%. Kerala is also one of the most developed states in India, with a high Human Development Index (HDI).
One of the main sources of income for Kerala is remittances from Keralites working abroad. In 2018, remittances from Keralites working abroad amounted to $16.3 billion. This is more than the state’s total revenue from taxes.
The remittances from Keralites working abroad are used to support their families in Kerala. They are also used to invest in businesses and real estate in Kerala. The remittances have a significant impact on the economy of Kerala. They help to reduce poverty and improve the standard of living of the people of Kerala.
The other options are not significant sources of income for Kerala. Foreign direct investment (FDI) is a relatively small amount of money. Lottery winnings are also a small amount of money. Export of handicrafts is a small industry in Kerala.
In conclusion, the correct answer is C. Remittances from Keralites working abroad.
