Consider the following:
Which of these is/are component(s) of internal debt?
Internal debt refers to the portion of government debt that is raised from domestic sources within the country. It represents the government's borrowing from its own citizens, financial institutions, and the central bank. The components listed are integral parts of India's internal debt structure:
Since all three items listed (market borrowing, treasury bills, and special securities issued to the RBI) are standard components of internal debt, option (D) is correct.
Options (A), (B), and (C) are incorrect because they exclude one or more valid components of internal debt. Internal debt comprehensively includes market borrowings, treasury bills, and special securities issued to the RBI. Therefore, any option that does not encompass all three components is incomplete and inaccurate in describing the full scope of internal debt.
