I want to know the exact concept of acknowledging comments.

There is a challenge

If you have any questions, please leave a comment.

It seems that you are asked to write about 10 to 20 comments.

In this case,

If I post a post and many comments are posted, including the administrator's, and I have to reply to all of them,

1. Is only one comment per post allowed?

2. Or, are comments that reply to one post recognized?

3. I hope the concept of replying to comments is also organized.
