The primary source of revenue for the Karnataka government:

Property taxes
Grants from the Central Government
Commercial taxes (GST, excise, etc.)
Income taxes

The correct answer is C) Commercial taxes (GST, excise, etc.).

Commercial taxes are the primary source of revenue for the Karnataka government. In 2020-21, commercial taxes accounted for 44% of the state’s total revenue. The other major sources of revenue for the state are income taxes (22%), grants from the central government (17%), and property taxes (11%).

Commercial taxes are levied on goods and services that are sold or consumed in the state. The most important commercial taxes in Karnataka are the value-added tax (VAT), the excise duty, and the luxury tax. The VAT is a tax on the sale of goods and services, while the excise duty is a tax on the manufacture of goods. The luxury tax is a tax on goods that are considered to be luxury items.

The Karnataka government collects commercial taxes through the Commercial Tax Department. The department has a network of offices across the state, and it is responsible for assessing, collecting, and auditing commercial taxes.

The revenue from commercial taxes is used to fund a variety of state government programs and services, including education, health, infrastructure, and social welfare.
