The correct answer is option 2: Finance Bill. The Finance Bill is a bill proposed by the Government that outlines the collection of revenues for a year. It includes provisions related to taxes, duties, and other sources of revenue. This bill is presented in the Parliament and is usually passed every year to authorize the Government to collect taxes and regulate the finances of the country.

Option 1: Economic Bill is incorrect because it does not specifically relate to the collection of revenues for a year. It may cover a broader range of economic policies and reforms.

Option 3: Supplementary Bill is incorrect because it usually refers to a bill introduced to make amendments or additions to an existing legislation or Bill.

Option 4: None of the above is incorrect because the Government does propose the collection of revenues for a year through the Finance Bill.
