Solution

The correct option is B
55°

From the given figure,

$∠ E C D = 180^{\circ} - 150^{\circ} = 30^{\circ}$ (sum of interior angles on the same side of the transversal is 180 $^{\circ}$ )

$x = ∠ B C D = 25^{\circ} + ∠ E C D$ (alternate interior angles)
$\Rightarrow 25^{\circ} + 30^{\circ} = 55^{\circ}$
