Answer:
Correct choice is D
Step-by-step explanation:
Notion [tex]\overrightarrow{CD}[/tex] 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 [tex]\overrightarrow{DC}[/tex] has initial point D and goes in direction to point C (to the left).
Option B is false, because ray [tex]\overrightarrow{CA}[/tex] has initial point C and goes in direction to point A (to the left).
Option C is false, because ray [tex]\overrightarrow{EC}[/tex] has initial point E and goes in direction to point C (to the left).
Option D is true, because ray [tex]\overrightarrow{CE}[/tex] has initial point C and goes in direction to points D and E (to the right).
