Which key deletes text before, or to the left, of the insertion point? A. PageUp B. Delete C. PageDown D. BackSpace

The correct answer is D.

The Backspace key is located above the Delete key on most keyboards. It is used to delete the character to the left of the cursor. The cursor is the blinking line that indicates where text will be inserted.

The PageUp and PageDown keys are used to scroll up and down a page, respectively. The Delete key is used to delete the character to the right of the cursor.

I hope this helps!
