Answer:
d. leakage in spending in the economy.
Step-by-step explanation:
In the economy firms spend money on labour, input, and business expansion. While in the personal household there is spending on food, rent, and other expenses.
When money is taken out of this cycle and not used for a particular purpose then it is considered to be a leakage.
Leakages include taxes savings and imports.
Savings occurs when an individual has excess income and decides to reserve some for a future use. This fund does not have a particular use in the economy so it is considered to be a leakage.
