Hi @RanaAmmar,
You may not realize it, but you've posted your question in the global community of Canvas users. Unfortunately, we are not able to answer specific questions like this because we do not have access to your Canvas account, course or environment at all. This would be something you should reach out to your teacher about via whatever method they have told you they'd prefer (perhaps the Canvas inbox, email, phone, office visit, etc).
I hope this helps point you in the right direction. Even though this is not a direct answer to your question, I am going to mark it as the solution to help guide others who may have similar questions in the future.
