Consider the simplest macro model with demand-determined output,where AE = C + I.Suppose that actual national income is $900 billion and desired consumption plus desired investment is $890 billion.We can expect that

A) firms will see a decrease in inventories,and they will respond by increasing output,thereby increasing actual national income.
B) firms will decrease autonomous investment by $10 billion until equilibrium national income is reached at $890 billion.
C) firms will increase autonomous investment by $10 billion until equilibrium national income is reached at $900 billion.
D) actual national income will increase until equilibrium national income is reached at $900 billion.
E) firms will see an increase in inventories,and they will respond by decreasing output,thereby decreasing actual national income.
