The correct answer is A) State GST.
State GST is a major source of revenue for the Telangana government because it is a tax on goods and services that are consumed within the state. The state government collects this tax and uses it to fund its various programs and services.
Central grants are also a source of revenue for the Telangana government, but they are not as significant as State GST. Central grants are funds that are given to the state government by the central government. The central government gives these funds to the state government to help it fund its various programs and services.
Income tax is a tax that is levied on the income of individuals and businesses. The central government collects this tax and uses it to fund its various programs and services. The state government does not collect income tax.
Property tax is a tax that is levied on the value of property. The local government collects this tax and uses it to fund its various programs and services. The state government does not collect property tax.
In conclusion, State GST is the major source of revenue for the Telangana government. Central grants, income tax, and property tax are also sources of revenue for the state government, but they are not as significant as State GST.
