Answer:
A) exports are equal to imports.
Explanation:
As we know that, the formula to compute the GDP is shown below:
GDP = Consumption + Investment + Government purchase + Net exports
$7 trillion = $3.5 trillion + $1.4 trillion + $2.1 trillion + net exports
$7 trillion = $7 trillion + net exports
The net exports is zero that determines that exports are equal to imports
