It can be observed that point C and point B does not lie on the line n, so CB is not contained in line n.
The point C and point E lie on the line m, so CE is contained on the line m.
The ray BC has start point as B , where as ray CB has start point as C. So ray BC and ray CB are different.
The ray AD and ray AC both has same starting point A, where as end point of both ray AD and AC is collinear. So ray AD is same as ray AC.
The angle EAD is formed by the ray AE and ray AD. The statement angle EAD is created from AE and DA is wrong as ray DA is different from AD.
The angle ECB is created by the ray CE and ray CB with common vertex at C. So statement angle ECB is created from ray CE and CB is correct.
Answer:
Correct statements are,
CE is contained on line m.
Ray AD is same as ray AC.
Angle ECB is created from ray CE and ray CB.
