How should Grandmother's mediating role be understood in the emotional structure of the story?

Correct answer: She gives a frightened child a direction toward dialogue

The governing concept is mediation within a strained relationship. Grandmother recognises Kezia’s fear and creates opportunities through which the child can approach her father, especially by suggesting that Kezia make a birthday gift. She does not simply argue against the father or force an instant reconciliation; she provides a safe emotional route toward contact. This makes option C correct: Grandmother guides the frightened child toward communication and experience. Her role is supportive and connecting. She does not increase the fear, because her care gives Kezia confidence; she does not prove the father wrong; and she does not replace the Macdonald family, whose openness serves a different function as a contrast.
