Final answer:
Jonas changes the escape plan and flees earlier with the infant Gabriel to save him from being 'released', a euphemism for euthanasia in their community. The correct option is A.
Step-by-step explanation:
The question asks why Jonas does not follow The Giver's original escape plan in the novel 'The Giver' by Lois Lowry. In the novel, the escape plan is altered because Jonas must take Gabriel with him when he flees.
This sudden change in plans is necessitated by the imminent release of the infant, which is a euphemism for euthanasia in the context of the story.
Jonas, having developed a deep bond with Gabriel and understanding the true nature of 'release,' cannot allow this to happen and so decides to escape with the infant earlier than planned. The correct option is A.
