@devesh-mishra13
It looks like I am not able to reopen your PR on my end because there is already another open PR here for the same branch of main

#786

Here is what I suggested you do.

Add this SQL question with the revised changes to your new open PR here
#786

Then when it is reviewed, approved and merged, then you will need to update your main branch.

Then if you are interested in contributing more quiz questions after that, then I would suggest create a new branch that is not the main branch.
It is common practice in open source to create new branches that are not the main branch when making new contributions.
It makes for a cleaner process that way and keeps your main branch clean and easy to work with.

Here is a more in depth tutorial on git branches which will help in the future
