Answer:
The correct answer is option b.
Step-by-step explanation:
A surplus in the market for loanable funds is likely to cause a fall in the interest rate. At lower interest rate, people who need credit will demand more loanable funds. While the suppliers will provide less funds. So, the demand of loanable funds will increase and the supply will decrease.
This process will continue till excess demand will cause the interest rate to rise. The initial equilibrium will be restored eventually.
