Respuesta :

Answer:

the last one

Explanation:

The last sentence, “A vertical garden, or green wall, is a wall covered
with vegetation, vertical gardens are gaining
popularity around the world” is a run-on sentence.

There is a comma splice between “vegetation” and “vertical,” which makes the sentence a run-on sentence. To fix it, we could put a semicolon in place of the comma, and the sentence would not be a run-on anymore.
