Solution

The correct option is D $a = 1, b = 4, c = 6$ and $x = 2, y = 6, z = 3$
Here, $K_{2} C r_{2} O_{7}$ acts as a oxidizing agent.

Basically, Hydrogen and oxygen atoms are balanced on both sides of the equation.

The balanced equation is :
$K_{2} C r_{2} O_{7} + 4 K C l + 6 H_{2} S O_{4} = 2 C r O_{2} C l_{2} + 6 K H S O_{4} + 3 H_{2} O$

It is a redox reaction. After complete balance equation, the values of variables are: $a = 1, b = 4, c = 6, x = 2, y = 6, z = 3$ .

Option D is correct.
