Answer. 9th grade.
Explanation. That is when my school introduced it.
Answer:
I believe the answer would be D
Explanation:
'A' was immediately dropped out for the lack of a period at the end.
Think about what a comma is supposed to do, It's supposed to have a small pause in a sentence. If you read everything out loud It would be awkward to pause in the places the commas are suggested. Thus, inclining me to think the correct answer is D.
Hope this Helps!
