What is the main difference between the Backspace and Delete keys?

Correct answer: Backspace removes the character to the left and Delete removes the character to the right

The governing concept is cursor-based text editing. Backspace normally removes the character immediately to the left of the cursor, while Delete normally removes the character immediately to the right. Their exact behavior can vary in special selections or fields, but this is the standard distinction taught for text entry. The other options describe neither key, so option D is correct.
