Answer:
The correct option is B,$12 billion
Step-by-step explanation:
Using the formula for GDP given as Y = C + I + G + NX,the GDP of Sildavia is computed thus:
Y=GDP
C=Consumption of Household=$7 billion
G=Government expenditure=$3 billion
I=Investment=$3 billion
NX=Net exports(Exports-Imports)=($4-$5)=-$1 billion
Y=$7b+$3b+$3b-$1b
Y=$12 billion
The transfer does not feature in the GDP computation as it does not relate to any goods purchased
