Answer:
A) I planted shade evergreens and flowering trees, short, tall, and medium shrubs, and red, yellow, and white roses.
Step-by-step explanation:
To punctuate the sentence correctly we must separate each type of plant with a comma, and usually separate each category with a semicolon.
If you broke the sentence down into each different category it would be like this:
1. I planted shade evergreens and flowering trees
2. Short, tall, and medium shrubs
3. Red, yellow, and white roses
Put it all together: I planted shade evergreens and flowering trees, short, tall, and medium shrubs, and red, yellow, and white roses.
