الإجابة: B. Na – [Cl + HCO3]
Anion gap = Na − (Cl + HCO3), the measured cation minus the main measured anions; it is used to sort the causes of metabolic acidosis. Potassium is usually left out, and adding Cl/HCO3 to Na makes no sense.

A
ليش غلط
The anion gap is sodium minus the sum of chloride and bicarbonate, not Na + (Cl − HCO3).

B
ليش صح
Anion gap = Na − (Cl + HCO3), used in metabolic acidosis to work out the cause.

C
ليش غلط
Chloride and bicarbonate are subtracted from sodium; they are not added to it.

D
ليش غلط
The formula uses sodium, not potassium: AG = [Na+] − ([Cl−] + [HCO3−]).
