Solution

The correct option is A $C > A > B$
Solution :
As we know that: Oxidizing power decreases from top to bottom in the electrochemical series.
Elements are arranged in:
$C$
$A$
$B$
So, $C$ is at top and $B$ at bottom
So, $C > A > B$ is the order of their oxidizing power in electrochemical series.

Option A is correct.
