Answer:
He implies that the English care so little for the Irish people that they will not object to using Irish children for food.
Step-by-step explanation:
Jonathan Swift's "A Modest Proposal" is a satirical pamphlet/ proposal where he criticizes the English's approach in matters of the Irish society. The proposal highlights the poverty and problems in Ireland and how the English government/ monarchy is so far away from caring even a bit for them.
As seen in the given excerpt from the proposal, Swift declares that his new proposal will provide "something solid and real, of no expence and little trouble". Moreover, this new plan will "incur no danger in disobliging England", and that it will merely involve the children of Ireland and would rather be benefitting for the rich people. This seems to suggest that the English care little for the Irish people and that they will have no qualms with using Irish children for food.
Thus, the correct answer is the last/ fourth option.
