Solution

The correct option is B $F e O_{2}, h e a t - --- \to F e_{3} O_{4} C O, 600^{\circ} C - ----- \to F e O C O, 700^{\circ} C - ----- \to F e$
(b) is the correct answer because all the steps are that of iron extraction in a blast furnace.
(a) is wrong because
$F e C l_{3} + \frac{1}{2} O_{2} Δ - \to F e O C l + C l_{2} ↑$
(c) is wrong because $F e_{2} (S O_{4})_{3} Δ - \to F e_{2} O_{3 (s)} + 3 S O_{3} ↑$
(d) is wrong because $2 F e S O_{4} Δ - \to F e_{2} O_{3 (s)} + S O_{2} ↑ + S O_{3} ↑$
