Hey Pavani,
Are you talking about in Service Studio or are you trying to create your own page where you want to display the module type to an end user?
If it's the former, for extensions there will be "(extension)" shown behind the module name in grey text.
Blank and web responsive don't have much of a difference, web responsive already has a UI flow setup for you, but you can do this manually in blank aswell (so potentially they can be the same, but responsive does some stuff for you already).
I am taking about in service studio not trying to create by my own.
And I have checked for the extension behind the module name I didnot find the module type.
Pavani.
