a.$200 billion

b.$600 billion

c.$800 billion

d.$1,000 billion

option (d) $1,000 billion

Explanation:

Data provided in the question:

Gross domestic product = $3,500 billion

Consumption expenditure = $2,100 billion

Government expenditure = $400 billion

Investment = $800 billion

Net exports = $200 billion

Now,

National savings

= GDP - (Consumption expenditure + Government consumption)

= $3,500 billion - ($2,100 billion + $400 billion)

= $1,000 billion

Hence,

The answer is option (d) $1,000 billion
