Solution

The correct option is B I and III only

$y^{\circ} = u^{\circ}$
$x^{\circ} = l^{\circ}$
$w^{\circ} = z^{\circ}$
$x + y = u + w$
$l^{\circ} + u^{\circ} = u^{\circ} + w^{\circ}$
$x = t^{\circ} = w^{\circ} = z^{\circ}$
$z = w^{\circ} = t^{\circ}$
I and III are true

$y^{\circ} = u^{\circ}$
$x^{\circ} = l^{\circ}$
$w^{\circ} = z^{\circ}$
$x + y = u + w$
$l^{\circ} + u^{\circ} = u^{\circ} + w^{\circ}$
$x = t^{\circ} = w^{\circ} = z^{\circ}$
$z = w^{\circ} = t^{\circ}$
