AOutside Border
BTop Border
CInside Border
DExtemal Border
Answer:
D. Extemal Border
Read Explanation:
External Border
There is no option called "External Border" or "Extemal Border" in the drop-down menu. The correct technical term used by Microsoft for applying a border around the entire outside edge of a selection is Outside Border (or Thick Outside Border). Because "External" is not part of the official program terminology, it is the option that is not available.
When you click the drop-down arrow next to the Border Button, you are presented with standard geometric placement options:
Top Border: Applies a line strictly to the top edge of the selected cells or paragraph.
Outside Border: Applies lines around all four outer edges of the entire selection.
Inside Border: Applies lines to all the internal gridlines within a selected block of multiple cells or a table, leaving the outer edges completely blank.
