Which option is used to change boarder color

You can apply or change a style, border, or color of a table in your presentation. For example, you can apply or clear a table style (or Quick Style), erase lines from a cell, row, or column, change the border of the table, or change the background color of a table.

I couldn't find anywhere to change the border on <option> but the background-color can be changed using option{background-color: red;} but option{border: 1px solid red;} won't work.

Using option{border: 1px solid red;} works in firefox but it's bordering each option but I wanted to border on whole option groups.
