Answer:
I believe that the correct answer is D. Making jam is hard work, because it involves many steps to clean, cook, gel, and can the fruit.
Step-by-step explanation:
In this text, the author first explains how delicious homemade jam is. But then, they explain that it isn't easy to make, telling us all of the steps to clean, cook, gel, and can the fruit. The answer D sums up the text perfectly, just with smaller sentences.
Also, it's obvious that the author still thinks that canned jam is delicious, but none of the other answers apply.
Therefore, the correct answer is D.
Hope this helps! :D
