How does the pin-cushion incident become an irony of relationships in the story?

Correct answer: An act begun with love became a cause of fear and punishment

The governing concept is irony, especially the contrast between intention and result. Kezia wants to make a loving pin-cushion for her grandmother and uses papers she does not realise are important to her father. Her innocent act is therefore interpreted as wrongdoing, and the punishment increases the fear that already separates father and daughter. Option D is correct because a gesture motivated by affection produces the opposite emotional result: anxiety and punishment. Option A changes the intended recipient, B gives Grandmother an incorrect role, and C wrongly assigns the tearing of the papers to Macdonald.
