I believe C is correct, after reading through a few times I don't feel as though there is a defined topic sentence. The paragraph just seems to list facts without any true purpose.
No summary provided, however,
annual plants are those that grows for one season and dies. an example of annual plants are corn,beans,and some flowers that blossoms during the rainy season and dies through winter and summer.
Perennial plants are those that persist from season to season and never dies. Usually the remain dormant when the weather is hostile and blossoms when the weather is conducive.
The answer to your question is C
I’m guessing it’s A idk tho but try it :)
