Which of the following is NOT a source of government revenue?

Step 1: Analyze the question We are asked to find the option that does NOT list sources of government revenue. So three options list real revenue sources, and one lists something else.

Step 2: Concept Government revenue is money the government collects to fund its spending. Main sources include:

• Taxes (PAYE, VAT, company income tax, customs duties)
• Fees, licenses and fines (e.g. passport fees, driver's licenses, court fines)
• Grants, aids and loans (borrowing from home and abroad)
• Interest, dividends, profits and earnings from government-owned enterprises and investments (e.g. NNPC revenues, rent on government property)

Step 3: Check each option

• A. Grants, aids and borrowing: These are valid sources of revenue (external and internal funding).
• B. Taxes, fees, licenses and fines: These are the classic sources of government revenue.
• C. Interest, dividends, profits and earnings: These are income from government investments and parastatals, so they count as revenue.
• D. Personal income, disposable income and transfer earnings: These are concepts from household or national income analysis. Personal income and disposable income belong to individuals, not the government. Transfer earnings is a concept in factor pricing (the minimum payment needed to keep a factor in its current use). None of these is a way the government raises revenue. The government only gets a share of personal income indirectly, through taxation, which is already covered in option B.

Step 4: Answer The option that is NOT a source of government revenue is D.

Exam tip: In "which is NOT" questions, sort the options into familiar groups. Here, tax, borrowing, grants and returns on investments are all government revenue. Terms like "disposable income" and "personal income" point to households, so they stand out as the odd one.
