Hi @Md. Abdul Halim,
It could be because Microsoft Office applications are not installed on your computer. You can check whether Microsoft Office applications are installed by searching for it in the Start menu. If it is not installed, you will need to install them in order to have access to these applications. If these applications are installed but the options are still missing from the New menu, you can try repairing the installation of Office or reinstalling Office to see if it resolves the issue.
Also I found a thread which is similar to yours, you can take a reference to it:
Word, Excel and PowerPoint are missing from the right click new menu
Missing "New Word Document" in right click context menu
New Word doc option not appearing in right click menu
Hope my answer helps.
