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 $920 billion.We can expect that

A) firms will see an increase in inventories,and they will respond by decreasing output,thereby decreasing actual national income.
B) firms will decrease autonomous investment by $20 billion until equilibrium national income is reached at $900 billion.
C) firms will increase autonomous investment by $20 billion until equilibrium national income is reached at $920 billion.
D) firms will see a decrease in inventories,and they will respond by increasing output,thereby increasing actual national income.
E) actual national income will decrease until equilibrium national income is reached at $900 billion.
