Answer:
b. decreases; decreases; falls.
Step-by-step explanation:
A bond can be defined as a debt or fixed investment security, in which a bondholder (investor or creditor) loans an amount of money to the bond issuer (government or corporations) for a specific period of time. The bond issuer are expected to return the principal (face value) at maturity with an agreed upon interest (coupon), which are paid at fixed intervals.
In Economics, there are primarily two (2) factors which affect the availability and the price at which goods and services are sold or provided, these are demand and supply.
The law of demand states that, the higher the demand for goods and services, the higher the price it would be sold all things being equal. On the other hand, law of supply states that the higher the price of goods and services, the lower the supply.
Recession can be defined as a period of economic meltdown, in which there's a general decline in all economic activities such as trade.
Hence, when the economy slips into a recession, normally the demand for bonds decreases, the supply of bonds decreases, and the interest rate falls, ceteris paribus (everything else held constant).
