Solution

The correct options are
B $\frac{w}{x} = 0.25$
D $\frac{y}{z} = 1$
$T l_{2} O_{3} (s) + N H_{2} O H (a q) \to T l O H (s) + N_{2} (g)$

Oxidation state of $T l$ in $T l_{2} O_{3} = + 3$
Oxidation state of $T l$ in $T l O H = + 1$
Oxidation state of $N$ in $N H_{2} O H = - 1$
Oxidation state of $N$ in $N_{2} = 0$

$N$ is undergoing oxidation.
$T l$ is undergoing reduction.

Finding $n_{f} :$
$n_{f}$ of $T l_{2} O_{3} = 4$
$n_{f}$ of $N H_{2} O H = 1$

Cross multiplying these with $n_{f}$ of each other.
we get,
$T l_{2} O_{3} (s) + 4 N H_{2} O H (a q) \to T l O H (s) + N_{2} (g)$

Balancing the elements other than oxygen and hydrogen on both sides,
$T l_{2} O_{3} (s) + 4 N H_{2} O H (a q) \to 2 T l O H (s) + 2 N_{2} (g)$

Adding the $H_{2} O$ to balance the oxygen,

$T l_{2} O_{3} (s) + 4 N H_{2} O H (a q) \to 2 T l O H (s) + 2 N_{2} (g) + 5 H_{2} O$

Hydrogen is already balanced.
Charges on both sides is also balanced.
So, it is the final balanced equation.

So, the value of $w, x, y, z$ is $1, 4, 2, 2$ respectively.
$\frac{w}{x} = \frac{1}{4} = 0.25 \frac{y}{z} = \frac{2}{2} = 1$
