How to transfer User options from codeunit to the global function of a table via c/al code

I need to write a codeunit that will be called in the C/AL of the custom table that will transfer user options to the C/AL code.
From the option list the code works perfectly on the onValidate() function:

Could you you please be more specific about your requirements ? What is your goal, what do you want to achieve, in business terms? (Writing a codeunit is not a goal, transferring some data from one place to another might be)

Still not sure if I understand correctly.

Anyway - the codeunit can have a table as a parameter. You can pass your rec (your custom table) to the codeunit call in Toxity - OnValidate, like this

Toxity - OnValidate
CODEUNIT.RUN(CodeunitID,Rec)

Then inside the codeunit's OnRun trigger you can have your code changing values in your custom table (the one passed in CODEUNIT.RUN call:

OnRun(Rec : your custom table)
WITH Rec DO BEGIN
  IF "Custom Toxity" = 1  THEN
    "Custom Description" := 'Caution';
  IF "Custom Toxity" = 2 THEN
    "Custom Number" := 6;
 IF "Custom Toxity" = 3 THEN
    Commission := 99.0;
END;

I hope this answers your question. Not sure why do you need to have this in a separate codeunit, and why having the code in the Toxity - OnValidate trigger is not good enough. The only purpose I can think of is add flexilbility and enable different classification by specifying different codeunit ID to be run from Toxity - OnValidate in some setup, and that those codeunits will be added to your solution at later stages.

Unless the ID of the codeunit in the CODEUNIT.RUN(CodeunitID,Rec) line is supposed to be configurable somehow (you specify the id of the codeunit to be run in a variable which is populated eariler in the code from some sort of setup) the Toxity - OnValidate trigger is the best place to put this sort of validation code and it makes a very little sense to move the code to a separate object outside the Toxity - OnValidate trigger

Why not add a function in codeunit and call that function from onvalidate ? You can pass any variables that you want .
Instead of CODEUNIT.RUN, just call that NewCodeUnit.DoThisFunction.

Putting it in a separate codeunit, makes it easier to maintain and update in the future.

Having two instead of one objects would not make a big different managing the permissions. Normally once we setup the permission properly, we hardly change it in the future anyway.
It also depends on the requirement and personal preferences. Sometimes it makes sense to put simple codes in one place. However, I found out that normally we can always reuse the functionality elsewhere, so it is easier to maintain it if we have a separate codeunit (instead of putting it on the OnValidate).
Also when working with multiple developer, it is easier to spot and merge objects.
