Answer:
I believe that the correct answer is D.) Morning glories and sunflowers are much easier to raise than orchids.
Step-by-step explanation:
The whole text explains how "Orchids are wonderful flowers for a beginner to raise," as well as how easy they are to take care of. This is the authors claim. So the fact that morning glories and sunflowers are easier to raise than orchids completely clashes with the theme the author is trying to portray.
Therefore, the correct answer is D.) Morning glories and sunflowers are much easier to raise than orchids.
Hope this helps! :D
