The accurate representation of macroeconomic equilibrium in an open economy is captured by Y = C + I + G + (X - M), where output equals consumption, investment, government spending, and net exports. Here option A is correct.
In macroeconomic equilibrium in an open economy, the correct equation is A. Y = C + I + G + (X - M). This equation represents the expenditure approach to GDP in an open economy.
Y (output or income) is equal to consumption (C), investment (I), government spending (G), and net exports (X - M), where net exports are the difference between exports (X) and imports (M).
In an open economy, the inclusion of net exports accounts for international trade, reflecting the fact that economic agents can engage in cross-border transactions.
Option B (Y > AE) is not accurate in describing macroeconomic equilibrium. The equality Y = AE represents equilibrium where aggregate output (Y) equals aggregate expenditure (AE), which includes consumption, investment, government spending, and net exports. The correct equation is Y = C + I + G + (X - M), not Y > AE.
Option C (Y = C - I - G - NX) is incorrect. It seems to represent an inaccurate expression for the equilibrium condition in an open economy. Here option A is correct.
Complete question:

A. Y = C + I + G + (X - M).
B. Y > AE
C. Y = C - I - G - NX.
D. Y = 0
