Which of these writing activities should happen during the revision stage? A. Make sure that each of your paragraphs has all the details it needs.
B. Correct any mistakes in spelling, grammar, or punctuation.
C. List all of your ideas about the topic.
D. Write each of your main ideas as a paragraph with supporting details.

A. Make sure that each of your paragraphs has all the details that it needs

Explanation:

Let's look at every option and see why they are wrong. D is wrong because while that is something that you should do, that's something you do when you write the first draft. Revising is for when you are done with the first draft and are polishing it to submit. C is also wrong due to the same reason. That is something you do after receiving the prompt you are writing about, not something you do in the revising phase. While B sounds like something you would do in the revising phase, it is something you do after in the editing phase. The difference between the two is the revising phase is for making sure your supporting details are there and your paragraphs are organized correctly, while you look over your paragraph for grammatical errors and things like that in the editing phase.

i think its d, but grammarly says none

explanation:

the present continuous is a verb tense which is mainly used to indicates that an action is in progress at the moment of speaking.  

it is formed using: person + verb to be (am/is/are) +verb + - ing form  

example: i am studying at this moment .

in addition, the present continuous is also used in order to express things that will or will not happen in the near future.

example: i am having dinner with some friends tonight.

the speaker sometimes   uses it   to express that an action is repeated and it causes irritation on the part of the speaker

example: my sister is constantly complaining about everything.
