Solution

The correct option is C
w = 2, x = 3, y = 4, z = 3

Balance the iron:
$F e_{2} O_{3} (s) + C (s) \to 2 F e (s) + C O_{2} (g)$
Balance the oxygen:
$2 F e_{2} O_{3} (s) + C (s) \to 2 F e (s) + 3 C O_{2} (g)$
Balance the iron again:
$2 F e_{2} O_{3} (s) + 3 C (s) \to 4 F e (s) + 3 C O_{2} (g)$

and carbon is already balanced.
