Answer:
A. The demand for money falls and the interest rate falls
Explanation:
As in general sense when the price level falls it means that the goods will cost less than the earlier stated cost. As the cost will fall the value of money will increase in terms of goods.
Accordingly an individual can buy more goods with same amount of money. This will reduce the demand for money in the market.
Ultimately people will not borrow money and that the demand for loans will fall. Accordingly as banks earn through interest income on loans they will be ready to lend at a lower rate of interest.
Thus, option A is correct.
