Where is the screen rotation option ? (MacBook 2017, 12 inch)

Are you by any chance mirroring the internal display to that external?

You can't rotate if you are mirroring. Switch to extended display and it should offer rotation as an option - as shown in the screenshot posted by P. Phillips above.

Thanks , Its working now.

I dint know that rotation works only for extended display 😅

Great.

In old times one could rotate the internal display of a mac laptop, then this capability was removed, years ago.

I don't think many people used their laptops upside down or laying on one side...

My guess is that if we were to rotate a display that is mirroring the internal that would involve rotating the internal as well.

maybe Rotate the image on your Mac display - Apple Support

Don’t you see any options for rotation? Try holding down the Option key while clicking on Displays and/or when clicking on your specific display within System Settings.

The " Screen Rotation " on the Builtin Display of this machine ?

This may be available Only If the computer is using an External Display that is capable of Screen Rotation

If so refer to below image

That External Display does support this function

Looking at their Specification Sheet, I do not see anything specifically mentioning the Actual Monitor Display is capable to >> Physical Rotating <<

The Display of the Monitor to Physical Rotate from Landscape Mode to Portrait Mode is what I am trying to emphasis

Looking at another site, quoting the Features I do not see the ability for the Screen to be Physically Rotated on its Base

Ops 😎, think this is intended for OP

Hope your suggest works for them 👍
