Which statement regarding the diagram is true?

Step-by-step explanation:

In the figure attached

Option A : m∠ w × y = m∠y × z

                                 ( not true )

Option B : m∠ w × y < m ∠y × z

                           ( Not true because ∠w × y > ∠m ∠y × z )

Option C : m ∠ w × y + m∠y × z = 180°

                        True because these angles are supplementary angles.

Option D : m∠ w × y + m∠xyz = 180°

                           ( not true )
