Need HELP for Beginner Assignment

[RR_real]

Hi everyone, I'm a beginner and I’m currently working on an assignment that requires converting an orthographic projection to an isometric drawing in AutoCAD (beginner level).
 

I’ve attached the link to:

An image  of the assignment question

Option 1: my first isometric drawing

Option 2: my second isometric drawing

could someone please help confirm which option is correct?
I’d really appreciate any guidance so I don’t carry the same mistake forward.
Thank you in advance.https://imgur.com/a/nN0afna

Option2 is the correct answer.  For option 1 to be correct the orthographic views would need to include dashed lines to show the wall thickness of the vertical cylinder.  What you show is a hollow vertical cylinder with a zero wall thickness.
