Answer:
The answer is D
Explanation:
Because parallel means "(of lines, planes, surfaces, or objects) side by side and having the same distance continuously between them." - Google Dictionary
This means that if you draw two lines next to each other and no matter how far they go on, they will never meet.
You can remember this by looking at the two L's in 'parallel' and seeing how they will never meet - because they are parallel to each other
Hope this helped you!!!
