Which of the following will be an effect of inflation?

During inflation, the general price level rises, which means money loses purchasing power over time. This dynamic creates winners and losers depending on whether one holds money or owes money.

Borrowers of money gain during inflation because they repay their loans with money that is worth less than when they originally borrowed it. If someone borrows 100,000 naira today and repays it after a period of significant inflation, the real value of that repayment is lower than the real value of what was borrowed. The borrower effectively repays less in real terms.

Conversely, money lenders (creditors) lose during inflation because the money they receive in repayment buys fewer goods and services than the money they originally lent out. Their real return is eroded. Wage earners, especially those on fixed wages, also lose because their nominal pay buys less as prices rise. While borrowing may increase during inflation (as people try to buy assets before prices rise further), the question asks about an effect of inflation, and the direct economic effect is that borrowers gain at the expense of lenders.
