Which of the following steps would remove column z from a worksheet? a. select column z and press the backspace key. b. click anywhere in column z and press the delete key. c. select column z, and in the delete drop-down menu select delete sheet columns. d. click any cell in column z, right click and select delete in the pop-up menu.

c. Select column Z, and in the Delete drop-down menu select Delete Sheet Columns.

Explanation:

To delete an entire column, and not just its contents, you need to first select the whole column (by clicking on the title of the column - here 'Z') then ask to delete the column.

All other options presented as possible answers will delete the contents of the selected cells (answers B and D would erase just one cell's contents) but would not remove the column.  Answer A would erase all the contents of the column and would leave you with an empty Z column.
