Explanation:

First statement is correct while second and third is incorrect.
1. Revenue deficit = Total revenue expenditure – Total revenue receipts.
2. Fiscal deficit = Total expenditure – Total receipts excluding borrowings.
3. Primary deficit = Fiscal deficit-Interest payments.
Fiscal deficit is defined as excess of total budget expenditure over total budget receipts excluding borrowings during a fiscal year. In simple words, it is amount of borrowing the government has to resort to meet its expenses. A large deficit means a large amount of borrowing. Fiscal deficit is a measure of how much the government needs to borrow from the market to meet its expenditure when its resources are inadequate.
Primary deficit is defined as fiscal deficit of current year minus interest payments on previous borrowings. In other words whereas fiscal deficit indicates borrowing requirement inclusive of interest payment, primary deficit indicates borrowing requirement exclusive of interest payment (i.e., amount of loan).
Effective Revenue Deficit is the difference between revenue deficit and grants for the creation of capital assets. In other words, the Effective Revenue Deficit excludes those revenue expenditures which were done in the form of grants for the creation of capital assets. Effective Revenue Deficit was introduced in the Budget of 2011-12 for the first time. In 2012-13, Effective Revenue Deficit was introduced as a fiscal parameter.
