    You can pass $event in the function and use event.target to get the required data in your ts file.

You may not be able to pass these values as written in your code, as item, m, k are not in scope. Instead, you can pass $event to the handler function and use event.target.selectedOptions[0].parentElement to access the selected optGroup element.
