Final answer:
In the novel, Sanaubar reacts to Hassan's deformity with disgust, refusing to hold her newborn son and mocking his harelip.
Step-by-step explanation:
The character Sanaubar's reaction to Hassan's deformity in the novel is one of disgust. Sanaubar ridicules her son's harelip, demonstrating a cruel disposition toward Hassan's physical appearance.
After giving birth, she even refuses to hold Hassan, highlighting her revulsion and lack of maternal affection. Sanaubar's behavior contrasts sharply with the sympathetic and loving attitudes displayed by other characters in Hassan's life.
