On which occasion did Kezia think of making a gift for her father?

Correct answer: Birthday

Kezia thought of making a gift for her father on his birthday. In the story, she decided to prepare a pincushion as a personal present because she wanted to show affection in a simple, childlike way. The important detail is the occasion, not the later mistake involving the stuffing. She accidentally tore the sheets of her father’s speech and used them inside the pincushion, but that accident does not change the occasion for which the gift was planned. New Year, School Day, and Exam Day are not connected with this event. Thus, option A is correct and helps distinguish the intended birthday gift from the unfortunate incident that followed.
