What kind of motivating force is Grandmother's role in relationship repair?

Correct answer: She pushes the child toward dialogue and closeness

The governing concept is mediation within a family relationship. Grandmother does not encourage Kezia to remain afraid of her father or to withdraw from him. Instead, she creates opportunities for Kezia to know him better, including suggesting that Kezia make a pin-cushion as a gift for him. Although the gift episode goes wrong, Grandmother’s larger role is to open a path toward communication and emotional closeness. Option D is therefore correct. Options A and B wrongly describe her as a source of separation, while C gives importance to the Macdonald family rather than to Grandmother’s function. Her influence helps Kezia move from fear and silence toward understanding.
