The correct answer is A. Select the text and press the delete button.
To cut text, you can select the text and then press the Delete button, select Edit > Cut from the menu, click the Cut button on the toolbar, or press Ctrl + X.
Pressing the Delete button deletes the selected text. This is not the same as cutting the text, which removes it from the current document but stores it in the clipboard so that it can be pasted elsewhere.
Selecting Edit > Cut from the menu or clicking the Cut button on the toolbar also cuts the selected text.
Pressing Ctrl + X is a keyboard shortcut for cutting text.
I hope this helps!
