New deep kitchen sink - disposal too low for drain?

[chicagoResident]

I want to replace my kitchen sink with one with deeper bowls. The new lower bowls will result in the disposal discharge tube being near or at the level of the sewer waste pipe. In the image, diagram A is the current layout, which is in code. But in diagrams B and C, the level of the discharge tube is lower. Are either B or C within code? The difference is small but under my sink a fraction of an inch may matter. Please refer to the diagram. Thank you for your help.

Water doesn't flow uphill unless pumped. While a disposer acts like a pump, you don't use it all of the time, and therefore, the trap arm can't be above the outlet of the disposer.

Was that a "no" or a "yes" or a "dunno"?

Those all look good. I don't know what I was looking at the first time.

My current rough for kitchens is now 16" from the floor.
Older kitchens were roughed at 19" or higher.
The disposer must drain by gravity. I see way too many 50,000 kitchen remodels where the plumbers was not consulted before the cabinets went in.
If the drain is high, the water never drains from the disposer. That smelly water rusting the unit out is not my idea of a quality job.

Thy are ALL "legal" because none trap water in the disposer.
