Answer:
B) The interest rate would decrease and the quantity of loanable funds would increase.
Explanation:
If workers can increase their tax deferred savings, then the amount of money available for loanable funds will increase. In other words the supply of loans will increase. This should cause a decrease in the price of credits, since the price of credits is the interest rate. If the interest rate decreases, the demand for loans will increase until a new equilibrium point is reached.
