Answer:

C. borrowing

Brief Explanations:

When the Federal - Reserve (Fed) adjusts interest rates, it directly affects the cost of borrowing for consumers. Higher interest rates make borrowing more expensive, and lower interest rates make it cheaper. While interest rates also influence saving, spending, and investing, the most direct impact is on borrowing.
