| deepseekr1 | The question asks when investment demand is most likely to increase. Investment demand is influenced by factors such as business confidence, costs, interest rates, and economic growth. - **A. Real GDP decreases**: A decline in real GDP signals a weaker economy, which typically reduces business confidence and investment. This is unlikely to increase investment demand. - **B. Cost of capital equipment rises**: Higher costs make investments less profitable, discouraging spending on capital. This would decrease, not increase, investment demand. - **C. Investor optimism improves**: Increased optimism about future economic conditions encourages businesses to expand production and invest in capital. This directly boosts investment demand. - **D. Real interest rate rises**: Higher borrowing costs reduce the incentive for businesses to take loans for investment, lowering investment demand. The correct answer is **C**, as improved investor optimism stimulates investment. Answer: C |
