Answer:

Correct choice is D

Explanation:

Notion
$\overrightarrow{CD}$ means that you have to consider RAY with initial point C that goes in direction to point D (to the right).

Option A is false, because ray
$\overrightarrow{DC}$ has initial point D and goes in direction to point C (to the left).

Option B is false, because ray
$\overrightarrow{CA}$ has initial point C and goes in direction to point A (to the left).

Option C is false, because ray
$\overrightarrow{EC}$ has initial point E and goes in direction to point C (to the left).

Option D is true, because ray
$\overrightarrow{CE}$ has initial point C and goes in direction to points D and E (to the right).
