The correct answer would be, death is a terrifying topic that even adults can't discuss.
Abigail who has heard adults talking about the death, senses that her mother is avoiding the topic and has come to the conclusion that death is a terrifying topic that even adults can't discuss.
Explanation:
People usually avoid discussing topics like deaths in front of children. This is because incidents like deaths leave deep footprints on the mind of children and they might get horrified due to the discussion upon this topic, so parents usually avoid discussing deaths.
The same did Abigail's parents. They did not tell him clearly that his grandfather is dead, rather they told him that his grandfather is no more, while leaving house for the funeral and leaving him home with the babysitter. So Abigail concluded that death is such a terrifying topic that even adults can't discuss it.
