Answer:
A. The real interest rate is higher in Alpha, but the nominal interest rate is higher in Beta.
Explanation:
Real interest rate: the interest rate after taking into consideration the inflation effect, which decreases the interest real return.
real-rate = nominal - inflation
Alpha: 7% - 3% = 4% real interest rate
Beta: 10% - 8% = 2% real interest rate
Alpha real interest rate is higher than Beta
alpha nominal rate: 7%
beta nominal rate: 10%
the Beta nominal rate is higher than Alpha.
This makes option A the only correct answer.
