Answer:
Option (C) is correct.
Explanation:
Private saving refers to the savings of the households which cannot be used for the consumption and tax payment.
Public saving refers to the savings of the government.
Private savings:
= Income - Consumption - Taxes + Transfer payments
= $12 - $9 - $3 + $2
= $2 trillion
Public savings:
= Taxes - Transfer payment
= $3 trillion - $2 trillion
= $1 trillion
