ANSWER
[tex]C. \: < \: ZXY[/tex]
[tex]D. \: \: ^\leftrightarrow_{YX}[/tex]
EXPLANATION
For the first option. ZX is not a ray, it is a line segment.
An angle is always formed at the letter in the middle
<XYZ is formed at Y.
But from the diagram, there is no angle formed at Y.
So option B is not a correct option.
Option C is a correct option because the angle
is formed at X
There is also line YX.
D is also a correct option.
