Hello @asadullah786
Your work is not 100% original, you have sections of your work showing you copy and past.

While you’re doing research and taking notes for your paper, make sure to record the source of each piece of information. One way that students commit plagiarism is by simply forgetting where an idea came from and unintentionally presenting it as their own.

While writing your paper, if you want to share an idea or a piece of information from a source, you must either paraphrase or quote the original text.

Do the corrections and do your possible best to stay away from such practice. Tag me when you done.
Thanks
