The answer is A
Sorry if I’m wrong
I believe the correct answer is B. end on a note that's likely to stick in the reader's mind.
If you want your essay to stick out from a bunch of other similar essays, you need to have a good 'punchline.' There has to be something in your conclusion which will make your readers remember the essay if you want to differ from a sea of other writers.
C and B are the best possible answers
A sentence with the word "apple" in it could be:
"My sister and I love to eat an apple with our snack."
Hope I helped!
