Question

\a modest proposal\
by jonathan swift
it is a melancholy object to those, who walk through this great town, or
travel in the country, when they see the streets, the roads and cabbin-
doors crowded with beggars of the female sex, followed by three, four, or
six children, all in rags, and importuning every passenger for an alms.
these mothers instead of being able to work for their honest livelihood, are
forced to employ all their time in stroling to beg sustenance for their
helpless infants who, as they grow up, either turn thieves for want of work,
or leave their dear native country, to fight for the pretender in spain, or sell
themselves to the barbadoes.
i think it is agreed by all parties, that this prodigious number of children in
the arms, or on the backs, or at the heels of their mothers, and frequently
of their fathers, is in the present deplorable state of the kingdom, a very
great additional grievance; and therefore whoever could find out a fair,
cheap and easy method of making these children sound and useful
members of the common-wealth, would deserve so well of the publick, as
to have his statue set up for a preserver of the nation.
but my intention is very far from being confined to provide only for the
children of professed beggars: it is of a much greater extent, and shall take
in the whole number of infants at a certain age, who are born of parents in
effect as little able to support them, as those who demand our charity in
the streets.
as to my own part, having turned my thoughts for many years, upon this
which sentence from \a modest proposal\ is the best example of satire?
some persons of a desponding spirit are in great
concern about that vast number of poor people,
who are aged, diseased, or maimed.

thus the squire will learn to be a good landlord,
and grow popular among his tenants, the mother
will have eight shillings neat profit, and be fit for
work till she produces another child.

i have reckoned upon a medium, that a child just
born will weigh 12 pounds, and in a solar year, if
tolerably nursed, encreaseth to 28 pounds.

Explanation:

Satire uses irony/humor to criticize. This sentence absurdly presents selling children (implied by context of "A Modest Proposal") as a way for mothers to profit and work, mocking societal indifference to poverty by treating children as commodities, unlike the other options (A is concern, C is factual weight calculation).

Answer:

B. Thus the squire will learn to be a good landlord, and grow popular among his tenants, the mother will have eight shillings neat profit, and be fit for work till she produces another child.
