Which of the following is the most important source of financing the gross fiscal deficit of the Government of India?

Market borrowings (issuing government securities, bonds, treasury bills) are the primary source of financing India's gross fiscal deficit. The government borrows from the public, banks, and financial institutions by selling these instruments. While other options contribute, market borrowings constitute the largest share (typically 80%+) of deficit financing. Loans from state governments are negligible (states borrow from center, not vice versa), and other institutional loans are much smaller components.
