Solution

The correct options are
A $F e_{2} O_{3} + C R e d u c t i o n \to F e$
B $Z n O + C R e d u c t i o n \to Z n$
C $P b O + C R e d u c t i o n \to P b$
D $S n O_{2} + C R e d u c t i o n \to S n$
Reduction is loss of oxygens.
In all the above reactions the metal oxides are reduced to metals by the elimination of oxygens,so all are reduction ractions.
Hence options A,B,C & D are correct.
